spin [16.1K]

Answer:

126 apples

Step-by-step explanation:

Let the number of apples picked by Mary=m

Cindy picks 6 times as many as Mary= 6Xm=6m

John picks 8 times as many as Mary= 8Xm=8m

Altogether they picked a total of 135 apples.

m+6m+8m=135

15m=135

m=135/15

m=9

We want to determine how many apples John and Cindy Picked.

John Picked 6m apples

Cindy Picked 8m apples

Their combined total= 6m+8m =14m

Since m=9

14m =14 X9 =126 apples

John and Cindy picked a total of 126 apples
