Using the formula y = kx
80 = .5k
k = 160
y = 160*2.25
y = 360

Let's say Jackson's age now is x.
In 20 years, (so 20+x), Jackson seven years ago will be 2/5ths of that age.
So 2/5(20+x)=x-7
Then you solve the equation
8+2/5x=x-7
15=3/5x
x=25
Jackson is 25 years old.
Let's check our answer! In 20 years, Jackson will be 45. 7 years ago, he was 18. 2/5 of 45 is 18. Our answer is correct!
You have 6 variables with 2 levels each. Thus 2*2*2*2*2*2 or 2^6 or 64.
