Question

Mike is three years older than his wife Karen.

Karen is five times as old as her son George.
Suppose George is g years old.
a. Write an expression, containing g, for Karen's age.
b. Write an expression for Mike's age.
c Work out the ages of the three people, when g=5.
d Work out the ages of the three people, when g=7.

Answer 1

1. Karen= g^5 (not sure)
2. Mike = g^5 + 3 (not sure)

3. Karen = 25

Mike = 28

4. Karen = 35

Mike = 38

Explanation:

1. if george age was g

karen age= g x 5 = g5

2. mike age= gx5 + 3

3. g = 5

karen age= 5 x 5 = 25

mike 25 + 3

4. g = 7

karen = 7x5 = 35

mike = 35 + 3

(i dont know if this correct or not but it my opinion)
