Shaunda said that buying 4 towels for $17 was a better buy than buying 2 towels for $9. She found her answer by doubling the terms in the ratio 9/2 and comparing the first terms in the ratio. Is she correct? Use unit prices to support your answer

Respuesta :

Answer:

The cost for a towel at 4 for $17 is:

17/4 = 4.25 $/towel

The cost for a towel at 2 for $9 is:

9/2 = 4.5 $/towel

So Shaunda is correct, as the cost per towel for 4 at $17 is lower.
