Answer:
C. The equation has two valid solutions and no extraneous solutions.
Step-by-step explanation:
See attached file for complete work.
You have to multiply every number!!
Example: 8 x 6 x 3 x 3 x 4
6% of 20 is 1.2. If you add 1.2, you get 21.30 making the answer c.
1- $52 {40+12(1)=}
5- $100 {40+12(5)=}
10 - $160 {40+12(10)=}
50 - $640 {40+12(50)=}
