A deposit of $2,500 grew to $3,325 after 6 years. What is the final value of a deposit of $7,500 at the same interest rate for the same period of time?

(josue) 16.8/7 = $2.4 per lb
(ricardo) 12.75/5 = $2.55 per lb

ricardo is incorrect because if you solve for the price per pound ( price/amount ), josue paid $2.40 for each pound of pretzels while ricardo paid $2.55 per pound. ricardo ended up paying more.
