The two line segments shown represent that Pierce has a total of 15 Penn and Wilson tennis balls. (p+ w = 15), and he has four times more Wilson balls than Penn. (w = 4p}. How many of each type of ball does Pierce have?

A 7 Wilson and 8 Penn
B 8 Wilson and 7 Penn
C 9 Wilson and 6 Penn
D 12 Wilson and 3 Penn

Answer 1

p + w = 15
w = 4 p

p + 4 p = 15
5 p = 15
p = 15 : 5
p = 3
w = 4 * 3 = 12
