let’s use x for how many total burgers.
if there were 3 times more cheeseburgers than hamburgers, then there would be 4x total burgers.
to find the exact value of x, let’s divide 468 by 4 which equals 117.
1x117=117 so there were 117 hamburgers sold in friday.
check work: 117x3=351
351+117=468. ✅✅✅
