Question

A gym container holds 50 balls of two sizes and two colors. Twenty-two balls are large and red, 12 balls

are small, and 25 balls are green. How many of the balls are small and green.

Answer 1

Since only 12 balls are small, each color has 25, 22 red balls are large - that leaves 3 red balls that are small. 12 small balls total less the 3 red small balls - that leaves 9 green small balls.
