Answer to Problem 13CT

Joe age is 43 and daughter age is 13

Explanation of Solution

Given: Six years ago Joe foster was two years more than five times as old as his daughter. Six years from now he will be eleven years more than twice as old as she will be. How old is Joe?

Let a be the Joes current age and d be the daughter current age

Equations for six years ago

  a6=2+5(d6)a=8+5(d6)....(i)

Equations for six years from now

  a+6=11+2(d+6)...(ii)

Substitute equation one in second

  8+5(d6)+6=11+2(d+6)14+5d30=11+2d+125d16=2d+233d=39d=13

Substitute d=13 in equation one

  a=8+5(d6)a=8+5(136)a=43

Hence, Joe age is 43 and daughter age is 13
