Jonah is going to the store to buy candles small candles cost $3.50 large candles cost five dollars he needs to buy at least 20 candles and he can’t spend no more than $80

Jonah would buy 20 small candles because when you multiply the cost for 1 small candle times the amount you'll need in this case it's 20 you'll get $70 which is how much he'll spend on getting 20 small candles which isn't over his budget of $80
