x + 30% x = 97.5 $
x+ 0.3 x = 97.5
x(1+0.3) = 97.5
1.3 x = 97.5
x= 97.5/ 1.3= 75 $ its original price

Answer:
$ 3,062.61
Step-by-step explanation:
Account Balance= 2,500(1+ .07/1)^3
The answer is 4.968 so rounded it would be 5.
Equation 1) y = 3 - x
Equation 2) 8x + y = -4
Rearrange equation 1 so that x and y are on the same side. To do so, you add x to both sides.
1) x + y = 3
2) 8x + y = -4
Subtract equations from each other.
-7x = 7
Divide both sides by -7.
x = 1
Plug in 1 for x in the first equation.
y = 3 - x
y = 3 - 1
Simplify.
y = 2
(1, 2) ==> x = 1, y = 2
