Answer is $100 original cost

Step by step

You know the total price is $200
You know the increase is 200% of x unknown

Your equation is 200% x = $200

Change your percent to a decimal by moving your decimal point two places to the left
200% = 2.00

2.00x = $200

Divide both sides by 2.00 to solve for x

2.00/ 2.00 x =$200 / 2.00

x = $100
