Question

Bahjo doesn't remember how much she spent at the store but she knows it was less than $25. All that she got from the store was 5 candy bars that cost c dollars and a gallon of water that cost $2.99. What is the maximum price that the candy bars could have cost her?

Answer 1

(25-2.99)/5 = 22.01/5 = $4.402

$4.40 = max price per candy bar
