Question

One brand of canned salmon is sold in four different sizes. What is the unit rate for each size to the nearest cent? If the cost is less than a dollar, put a zero to the left of the decimal point.

Answer 1

Unit Rate for Each Size (nearest cent):

Size A = 48 cents ($0.48)

Size B = 39 cents ($0.39)

Size C = 34 cents ($0.34)

Size D = 36 cents ($0.36)

Explanation:

The four different sizes are:

"Size A The 7 1/5 -ounce can costs $3.49.

Size B The 16 1/2 -ounce can costs $6.49.

Size C The 24 3/4 -ounce can costs $8.49.

Size D The 30 2/3 -ounce can costs $10.99."

To find the unit rate for each, we take the total price and divide by the total ounce. let's do this for each.

Size A =
`(3.49)/(7(1)/(5))=0.48`

Size B =
`(6.49)/(16(1)/(2))=0.39`

Size C =
`(8.49)/(24(3)/(4))=0.34`

Size D =
`(10.99)/(30(2)/(3))=0.36`

Unit Rate for Each Size (nearest cent):

Size A = 48 cents ($0.48)

Size B = 39 cents ($0.39)

Size C = 34 cents ($0.34)

Size D = 36 cents ($0.36)
