"For each day on the newpaper route you recieve $10.00 plus a fixed amount for each newspaper you deliver."

So you earn 10 + k*x dollars where k is the fixed number you earn per paper and x is the number of papers.

-------------------------------------------------------

"Currently you are earning $18.00 per day for delivering 80 newspapers. "

which means 10+k*x = 10+k*80 = 10+80k is the amount of money made. That amount of money made is $18, so

10+80k = 18

80k = 18-10

80k = 8

k = 8/80

k = 1/10

k = 0.10

So you earn $0.10 or 10 cents per paper.

-------------------------------------------------------

Now you are delivering 20 additional papers. So the total delivered is 80+20 = 100 papers

10+k*x = 10+0.10*100 = 10+10 = 20

The final answer is $20.00
