A 3-pound piece of salami costs $14.99. A 12-ounce package of the
same sliced salami costs $4.39. What is the difference in price per
4-ounce serving?
a. $1
b. $1.25
c. $1.46
d. $.21
First, we need to convert both prices to a per-ounce basis in order to compare them. The 3-pound salami is equivalent to 48 ounces (3 pounds x 16 ounces per pound), so the price per ounce is:
$14.99 ÷ 48 ounces = $0.3129 per ounce
The 12-ounce sliced salami is already in per-ounce form, and the price is:
$4.39 ÷ 12 ounces = $0.3658 per ounce
Now we can compare the two prices per ounce to find the difference. The difference in price per 4-ounce serving is:
($0.3658 per ounce x 4 ounces) - ($0.3129 per ounce x 4 ounces) = $0.1852 - $0.1252 = $0.06
Therefore, the answer is not listed.
