<human>:  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?
<bot>: Define a variable ** Let G be the price Gerald paid for his guitar.
How much did Gerald pay for his guitar? ** Then 0.8 * G = $200
How much did Gerald pay for his guitar? ** So G = $200 / 0.8 = $<<200/0.8=250>>250
#### 250
