A bag contains 10 white golf balls and 6 striped golf balls. A golfer wants to add 112 golf balls to the bag. He wants the ratio of white to striped golf balls to remain the same. How many of each should he add?

Algebra 
Henry,
(10+X) White balls.
6+(112X) Striped balls
(!0+x)/(6+(112x)) = 10/6
(10+X)/(118x) = 10/6
60 + 6x = 118010x
6x + 10x = 1180  60 = 1120
16x = 1120
X = 70 White balls added.
112x = 11270 = 42 Striped balls added.
