 ------> equation B
Multiply both equations by 100 both sides
 ---->
 ----> --> equation C
 --> equation C
 ----> equation D
 ----> equation D
substitute equation C in equation D

solve for y




Find the value of x




<em>Alternative Method</em>
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
the solution is the point (45,72)
therefore
