Question

A store sells a 9-ounce jar of mustard for $1.54 and a 15-ounce jar for $2.55. Is the cost of the mustard proportional to the number of ounces for each jar? Explain.

Answer 1

A store sells a 9-ounce jar of mustard for $1.54. 1.54÷9 = $0.171

a 15-ounce jar for $2.55. 2.55 ÷ 15 = 0.17

I'd say they are proportional
