You need A to do B. What did you get for A?

kitkat1 · Answer

s + c = total number of wafers                               Part 1.
3 x s  + 1 x c = total cost.

anonymous · Answer

ok. so you need to put the actual numbers from your problem into the equation

s + c = 22
3s + c = 30

kitkat1 · Answer

okay what do i do next?

anonymous · Answer

Subtract the bottom equation from the top to eliminate the variable c.|dw:1432584459032:dw|
