Question

John has four more apples than Kim. Kim has three times as many apples than Rob. Altogether, they have 46 apples. How many apples does each person have?

Answer 1

Explanation:

j=k+4

k=3r

j=3r+4

j+k+r=46

3r+4+3r+r=46

7r+4=46

7r=42

r=6, since k=3r

k=18, since j=k+4

j=22

j,k,r=22,18,6
