Question

The total cost for tuition plus room and board at State University is $12,584. Tuition costs $1,704 more than room and board. What is the tuition fee?

Answer 1

So let x be the cost for board
12,584 = 1704+x+x
12,584 = 1704+2x
12,584 - 1704 = 2x
10,880 = 2x
10,880/2 = x
5,440 = x
So the turion cost is 1704 + x
Which is 1,704+5,440 = 7144
