Question

which set of paper towels you sleep better by 9 rolls for $8.73 or 14 rolls for $12.32

Answer 1

To figure this out, first you need to find the rate, or how much 1 roll costs:

(I used x to represent 1 roll)

9x=8.73 -> x=0.97

14x=12.32 -> x=0.88

The 14 rolls for $12.32 is better because each roll costs 88 cents, which is 9 cents less than 97.
