Answer the following question, with explanation first.
Hendricks buys a guitar for $200, which is 20% less than what Gerald bought the same guitar for. How much did Gerald pay for his guitar?

250
Let G be the price Gerald paid for his guitar.

Then 0.

8 * G = $200.

So G = $200 / 0.

8 = $250.

.

So, the answer is 250
