A local hamburger shop sold a combined total of 510 hamburgers and cheeseburgers on Tuesday. There were 60 more cheeseburgers sold than hamburgers. How many hamburgers were sold on Tuesday?

225

Step-by-step explanation: if there are 510 hamburgers and cheeseburgers in total and there are 60 more cheeseburgers then hamburgers, we can use that that to make an equation. We can have hamburgers be X, and cheeseburgers be x+60. Using that, we can form the equation x+x+60=510. Then we solve that:

x+x+60=510

2x+60=510

2x=450

x=225

now we know that there were 225 hamburgers
