Answer 1

A certain brand of coffee comes in two sizes. An 11.3-ounce package costs $2.54.

An 11.3-ounce package costs $2.54.

Cost of 11.3 ounce package = 2.54

Then cost of 1 ounce = 2.54/ 11.3

Cost of 1 ounce = $ 0.224

A 27.8-ounce package costs $6.78.

Cost of 27.8 ounce package = 6.78

Cost of 1 ounce = 6.78/27.8

Thus, cost of 1 ounce = 0.24388

As, 0.224 is less than the 0.24388

But for 11.3 ounces it take $2.54 and with 0.24388 per price it take 2.755

Thus, 0.224 cost less

Answer :

Unit price for the 11.3-ounce package $0.22 per ounce

Unit price for the 27.8-ounce package $0.24 per ounce

The 11.3 ounce package
