If a unit price label has a unit price of 21.5 cents per pound, how much is the total price for an 8 pound package?
a. $0.37
b. $1.72
c. $2.69
d. $17.20

Given:
unit price per pound = 21.5 cents
bought 8 pound package

find: total amount paid for 8 pound package.

We need to convert cents into dollars to avoid confusion.

21.5 cents x 1 dollar / 100 cents = 21.5 dollar / 100 = 0.215 dollars

0.215 dollars * 8 pounds = 1.72 dollars.

my answer is B. $1.72
