A. Page 65 – Prob. #1 - THE SIDEWALK AROUND THE
GARDEN
We have a
garden that measures 17 feet by 20 feet.
We want to pour concrete for a 3-foot-wide sidewalk around the
garden. To make the forms for the
concrete, we will need to buy some 2 X 4 inch lumber. How many feet of lumber will we need just for
the perimeter of the walk? (Consider
both the inside and the outside perimeter)
B. Page 66 – Problem #5 - WAY TO SCORE
The Chicago
Bears score 18 points in a football game.
In how many different ways can the Bears score these points? Points are scored as follows:
A safety is 2 points,
A field goal is 3 points,
A touchdown is 6 points.
After a
touchdown is scored, the team may get
1 extra point for a kick,
2 extra points for a 2-point conversion, or
0 points if they fail on either of the above.
C. Page 103 – Problem #2 – THE BILLBOARD
Ed went to
work for an advertising company after school and on Saturdays. For his first assignment, he hired himself to
create a billboard. The billboard will
be 20 feet high and will proclaim his love for Candy (the girl, not the
sweets). He decided that each letter should
be 2 feet high and that there will be a 1/2-foot space between the bottom of
one line of words and the top of the next line of words. In addition, he wants borders measuring 1 ½
feet at both the top and the bottom of the billboard. How many lines of words can Ed fit onto the
billboard?
D. Page 133 – Problem #5 – COMMIC OF THE MONTH
I subscribe
to the Comic-of-the-Month Club. Each
month 1 can buy any number of the 48 titles offered by the club. The first month I bought five comics for
$3.07. The second month I bought two
comics for $1.72. The next month I
bought six of the club offerings for $3.52.
In May I bought three more for $2.17.
The club charges a fee for each comic and a fixed handling fee for the
entire order (for any number of comics).
How much would it have cost to buy all 48 titles at the same time?
E. Page 182 – Problem #2 – FAMILY DAY
Incredibly
Huge Motors is planning an employee-and-family day at the baseball park. The company has reserved 6000 seats with the
ball club. Each section of the ballpark
has 15 seats in each row and is 18 rows deep.
How many sections does the ball club need to set aside for the IHM
employees and families?
F. Page 217 – Problem #3 – QUIT WHILE YOU CAN
Smoking has
long been connected with serious diseases, such as lung cancer, emphysema, and
heart disease. Let’s estimate that for
every cigarette a person smokes, he or she loses anywhere from 10 to 15 minutes
of his or her life. Assuming the worst
(15 minutes of life lost for each cigarette), how much shorter would the life
span be of someone who smoke two packs a day for 35 years? (Each pack contains
20 cigarettes.) Answer in nearest tenth
of a year.
G. Page 274 – Problem #3 – KMRCL TV
A local TV station,
KMRCL, plans its number of commercials based on what type of show is being
broadcast. Each commercial is a minute
long. On daytime TV, the station runs 18
commercials every hour and then drops the number down to 16 per how for the
news. (Every day there are 8 hours of daytime
programming and 2 hours of news.) During
KMRCL’s prime time, which is 3 hours per day, the station runs 12 commercials
per hour. During the late-night movies,
KMRCL sells commercial time really cheap and runs 20 commercials per hour. Late-night movies are shown for 6 hours each
day. The station’s “other” programming,
which is on 5 hours per day, airs with 8 commercials per hour. For the sake of simplicity, assume that for
all seven days of the week each type of programming airs for the same number of
hours just described. Find how many
hours per week KMRCL airs commercials.
H. Page 298 – Problem #4 – DON’T FEED THE
ANIMALS
For a
camping trip, the five member Family family had
brought many bags of peanuts for snacks. Peanuts were everyone’s favorite, so they were
well stocked. Unfortunately, the
campground was populated by various animals who also
enjoyed an occasional peanut. The first
night, after the family went to bed, a raccoon visited their camp and ate five
of the bags of peanuts they had brought.
The next day, the Familys ate one-third of the remaining bags. That night, a beaver came to call and ate two
more of the bags. The next day, the
Familys consumed one-fourth of the remaining bags for breakfast. Then they took a boat trip, and they had to
feed one bag of peanuts to each of their five dogs to get the dogs to quite
down. That night, an elephant from a
nearby zoo came to the camp and ate four bags of peanuts. The next day, each member of the Family family ate one-ninth of the remaining bags. That night, a spotted owl ate half of the
remaining bags. The next day, there were
only four bags left. The Familys
couldn’t decide how to split them among the five of them, so they fed them to
the ducks. How many bags of peanuts did
the Familys bring with them on the camping trip?

orders can three basketball players be interviewed after a big game?
How about
four basketball players?
