Which equation models the problem?
Olayinka is participating in a bowl-o-thon to benefit the local hospital. Each sponsor will pay Olayinka $2 plus $0.10 per pin, x, that
she knocks down. How much will Olayinka raise per sponsor, B, for knocking down 52 pins?
OB-(2-0.10)
OB=0.10x + 2
O
B - (0.10 + 2)x
OB = 2x + 0.10
