100 - 20 = 80
179.00 = 80%
179.00 / 80 = 2.2375 = 1%
1% x 100 = 100%
So, 2.2375 x 100 = 100%
Therefore the original price was 223.75
Answer:
A negative number would be reasonable in the solution of the rate of the investment. It would be reasonable because Johnny started out with $41,745 in his account and ended up with $39,974 which means that the rate has to be negative.

Answer:
The solution to the system of equations be:
Step-by-step explanation:
Given the system of equations
x + y = 12
-x + 2y = 15
Let us solve the system of equations by elimination

adding the equations




solve 3y = 27 for y

divide both sides by 3

Simplify

For x+y=12 plug in y = 9

Subtract 9 from both sides

Simplify

Therefore, the solution to the system of equations be:
