A cafeteria sells sandwiches and chips. They earn $1 for each bag of chips sold and $6 profit for each sandwich sold. They sell 50 items in total for a profit of $115. Solve the systems of equations. Show all steps. How many sandwiches did they sell? How many bags of chips?

 

( I think something that might help is "c + s(6) = 115 )

 

ty in advance! ^^

s+c = 50

6s + 1c = 115   subtract bottom equation  from top equation

-5s = -65

 s = 13   sandwiches         then   13 + c = 50    means  37 chips
