This is an excellent practice for the solution of quadratic equations.
1*36=36 => (1,36)
2*18=36 => (2,18)
3*12=36 => (3,12)
4*9=36 => (4,9)
6*6=36 => (6,6)
9*4=36 => (9,4)
12*3=36 => (12,3)
18*2=36 => (18,2)
36*1=36 => (36,1)
We can see that the sum decreases until the two factors are close (or equal) and then increases again.
The pair of integers with a sum of 20 is therefore (2,18) or (18,2).

Answer:
Paper route earnings each week=($87.8-$37.8) / 10 =$5
If $5=20% we have to find how money is the 100%.
$5-----------------20%
x------------------100%
x=($5*100%) / 20%=$25
solution: $25.00
