B) The solution is (4, 200). This means that it will cost me $200 to go to either gym 4 times.
the equations given to you were: (C = 100 + 25x) and (C = 50x)
well, if you plug in 200 for C and 4 for x you get these equations, 200 = 100 + 25(4), and 200 = 50(x)
I solved both step-by-step below. 1. C = 100 + 25x plug in points 200 = 100 + 25(4) solve the parenthesis's 200 = 100 + 100 combine like terms 200 = 200 both sides are equal
2. C = 50x plug in points 200 = 50(4) solve the parenthesis's 200 = 200 both sides are equal
