Henry and Samantha have $30 to spend on bags of feed at the petting zoo. Each bag cost $3. Given that H and S represent the number of bags that Henry (H) and Samantha (S) bought, which expression can be used to represent the amount of money they had leftover?

Answer 1

The amount of money Henry and Samantha spent on bags of feed is given by the expression $3(H + S)$. The amount of money they had leftover can be found by subtracting this amount from the total money they started with, $30. Thus, the expression for the amount of money they had leftover is $30 - 3(H + S)$.
