Eric and Stephanie took their younger sister Melissa to pick apples.Eric picked 4 times as many apples as Melissa. Stephanie picked 6 times as many appples as Melissa.Eric and Stephanie picked 220 apples together

Answer 1

x + 4x + 6x = 220
11x = 220
x = 20 (Melissa)

20 + 4(20) + 6(20) = 220
20 + 80 + 120 = 220
100 + 120 = 220
220 = 220
Melissa picked x=20,
Eric picked 4(x)=4(20)=80,
Stephanie picked 6(x)=6(20)=120

Answer 2

Melissa picked 22 apples.

Eric picked 88 apples.

Stephanie picked 132 apples.

Let Melissa picked x apples.

Eric picked 4 times as many apples as Melissa, means 4x.

Stephanie picked 6 times as many apples as Melissa , means 6x.
