Question

A 17 ounce box of special K for $4.89 or a 21 ounce box of cheerios for $5.69. The better deal is?

Answer 1

Break down the price per ounce.

`(4.89)/(17) = 28` [28¢ per ounce]

`(5.69)/(21) = 27` [27¢ per ounce]

The box of Cheerios is the better deal.

Answer 2

The better deal is the 21-ounce one because its unit rate equals less than the 17-ounce one
