Question

Ann, Ben, and Cindy were eating strawberries. The ratio of the numbers of berries they ate is 5:5:7. If Cindy ate 30 strawberry fewer than Ann and Ben together, what is the total number of strawberries the three of them ate

Answer 1

170 strawberries

Explanation:

Let strawberries be x, then:

Ann ate 5x, Ben ate 5x, and Cindy ate 7x

7x+30 = 5x+5x

7x+30 = 10x

30 = 3x

10 = x

5x = 50

7x = 70

total: 50+50+70 = 170
