Question

Christy paid 80% of the original price to buy a tool set. She paid $89.00 for the tool set. What was the original price of the set?

Answer 1

Let be $ X of original price of tóol set.

payment account=$ 89.00

paid %= 80

solution, X- 80% of X = 89.00

or X-80/100× X=89.00

or X- 0.8X= 89.00

or 0.2X =89.00

or X =98.00/0.2

X= $445 answer
