Question

A 15-ounce can of store-brand tomato sauce costs $0.59 at a supermarket. The unit price of the sauce is listed on the shelf below the cans. To the nearest tenth of a cent, what should the listing show as the unit price.

Can someone please help me with this question?

Answer 1

Basically, you just divide 0.59 by 15 so you can find how much it costs per ounce and you round to the nearest tenth of a cent.

Therefore, 0.59 ÷ 15 ≈ 0.039 (actually 0.393 recurring but it says to round to the nearest tenth of a cent)

This means that one ounce of store-brand tomato sauce costs about $0.039.
