Asked by Midnight

Ann, Ben, and Cindy were eating Skittles. The ratio of the numbers of candies they ate is 5:5:7. If Cindy ate 30 Skittles less than Ann and Ben together, what is the total number of Skittles the three of them ate?
Answered by Reiny
A:B:C = 5:5:7 or 5x : 5x : 7x

Cindy ate 30 Skittles less than Ann and Ben together
-----> 7x = 5x + 5x - 30
-3x = -30
x = 10

5x = 50
7x = 70
They ate 50+50+70 = 170 of them
