6 fruit plates.
the answer is pretty obvious. it says he slices the cantaloupes into 6 equal sized servings and uses one of the servings to make fruit plates right? so 1 serving, 6 equal sized servings. therefore, 6 fruit plates.
When I solved it I got 26648.8
5(y - 4) = (5 * y) - (5 * 4) = 5y - 20
