You start from 0. Since Barton saves $20 each week, you have to move 20. So, from 0 you will go to 20, then 40, then 60 and the pattern goes on. At the same time you go right in a diagonal line. I attached a picture but I'm not sure you will understand it well.

The rate is usually given as a percent. So to find the discount, multiply rate by the original price. & to find the sale price, subtract the discount from the original price.
Answer:
-0.111c + 1 = 0.889c = c=1
Subtract 0.889c from both sides:
−0.111c+1−0.889c=0.889c−0.889c
−c+1=0
Subtract 1 from both sides.:
−c+1−1=0−1
−c=−1
Divide both sides by -1.:
-c/1 = -1/-1
Therefore, your answer is c=1
