Question

On Wednesday, a local hamburger shop sold a combined total of 380 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Wednesday?

Answer 1

95 hamburgers

Explanation:

hamburgers + (3) cheeseburgers = 380

solve for x

so you have x + 3x = 380

add the x's together to be 4x = 380

divide 4 from both sides

x = 95

so plug that into the equation, replace x with 95

Answer 2

The numbers of hamburgers sold is 95

Explanation:

If cheeseburgers sold equals 3 times hamburger

then we can say cheeseburger c = 3h, where h is hamburger

we can therefore say

h + 3h = 380

4h = 380

h = 95
