Ihave questions, two stores offer differently priced sales for the same paper towels, according to the table below. which store offers the better deal, based on a lower unit price per roll? store 1 store 2 paper towel rolls 12 15 price $3.30 $3.50 store has the better deal.

Store 1: 12 towel rolls for $3.30

Store 2: 15 towel rolls for $3.50

Divide 3.30 by 12 ⇒ 3.3/12 = $0.275 per roll - Store 1

Divide 3.50 by 15 ⇒ 3.5/15 = $0.233 per roll - Store 2

t = the number of years the money is invested

^ means raise to the power of
