Question

Can someone show me the steps to solve for the total amount of hamburgers and the total amount of cheeseburgers please?
Hamburgers sell for $3.00 each and cheeseburgers sell for $4.00 each. Bob sold a total of 400 burgers at the Marion Popcorn Festival, and he had total sales of $1,450. How many hamburgers did Bob sell? How many cheeseburgers did Bob sell?
