Question

A single-serving carton of yogurt costs 73 cents. A case of 8 single-serving cartons costs $5.36. How much is saved per carton by buying the yogurt by the case?

Answer 1

By buying the case, each carton will cost `6` cents less.

Explanation:

If a case of `8` single-serving yoghurt cartons costs `$5.36`, then the price of a single carton in the case will be:

`x=5.36/8`

`x=0.67`

Since a single-serving carton costs `$0.73`, the saving (`y`) per carton by buying the case will be:

`y=0.73-0.67`

`y=0.06`
