A postal carrier can deliver mail to about 900 addresses in one day. In the city of Huitt,
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
there are 26,942 residence. Workforce policy is required hiring 5% more carriers that are

estimated to be needed in order to compensation for vacation, sick days and so on. About
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
how many mail carriers must be hired to deliver mail to all of the Hewitt citizens each day?
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
A. 29 j.
B. 30 j.
C. 31 j. j.
D. 32 - (correct answer) -C. To find the number of mail carriers required, divide 26,942 by
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
900, which equals 29.94. Multiply this by 1.05 to get the extra 5% carriers, which results in
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
31.4 postal carriers. Rounding this down (since the number to the right of the decimal is
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
less than five) gives you a final number of 31 total mail carriers for the city.

Of $128 at a dog show, 50% or female. Among the females, three out of the four over the
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
age of four. How many of the dogs were females four years old or older?
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
, A. 64 j.
B. 48 j.
C. 16 j.
D. 32 - (correct answer) -B. If 50% of 128 dogs or female, then there were 64 female dogs
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
to start with (128×0.5 equals 64). Among those females, we were told that three out of four
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
were over the age of four. To convert it to a percentage to work with more easily, the
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
denominator must be 100. Multiplying anything by one or any of its forms is still the
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
number that we started with, so 3/4×20/20 = 75/100. (20/20 is a restated form of one, so
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
the amount we are talking about is the same, just stated in a different form) simplifying
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
75/100 gives us 0.75. Multiplying 64×0.75 equals 48, so we now know that they were 48
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
female dogs over the age of four at the dog show.

If 1 pound of Mesquite-smoked, deli - sliced turkey breast cost $7.98 at the second-largest
j. j. j. j. j. j. j. j. j. j. j. j. j. j.
grocery store in town, and each slice is about 1 ounce, what is the cost of five slices?
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
A. $1.34 j.
B. $2.37 j.
C. $2.49 j.
D. $3.99 - (correct answer) -C. There are 16 ounces in a pound. Therefore, if a pound of
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
smoked deli turkey breast cost $7.98, and each slice is about 1 ounce, then one slice cost
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
about $.50 (0.49875). Multiply this by five to get the cost of five slices.
j. j. j. j. j. j. j. j. j. j. j. j. j. j.
$0.49875 for one slice times 5 ounces equals $2.49375 equals $2.49 j. j. j. j. j. j. j. j. j. j.

B. 2950 cubic feet
j. j. j.
C. 3295 square feet
j. j. j. j.
D. 3795 cubic feet - (correct answer) -D. The formula for the volume of an object with
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
parallel sides and right angle corners is length L times width W times height H, or L x W x H

Jonathan spent four hours studying, one hour raking leaves, 30 minutes doing laundry,
j. j. j. j. j. j. j. j. j. j. j. j.
and two hours watching TV. What percent of his time was spent studying?

A. 46.6% j.
B. 50% j.
C. 53.3% j.
D. 57.1% - (correct answer) -C. First, add all the blocks of time together 4 hours +1 hour

+.5 hour +2 hours equals 7.5 hours total
j. j. j. j. j. j. j.
now multiply the time spent studying (four hours) by 100 and divided by the total time
j. j. j. j. j. j. j. j. j. j. j. j. j. j. j.
4×100 = 400 j. j.
