Maria and liam work in a banquet hall. maria earns a 20% commission on her food sales. liam earns a weekly salary of $625 plus a 10% commission on his food sales. what amount of food sales will result in maria and liam earning the same amount for the week?

Let us say that S is the total food sales therefore we can create the following equation:

0.20 S = 625 + 0.10 S

Solving for S:

0.10 S = 625

S = 6250

Therefore the food sales should amount to $6,250
