Option C is correct
$525
Step-by-step explanation:
As per the statement:
You are president of the high school band booster club. You have arranged for the school’s jazz band to perform at a local coffee shop for three hours. In exchange for the performance, the booster club will receive three-quarters of the shop’s gross receipts during that three-hour period.

y the dependent variable representing the booster’s share
x the independent variable representing the gross receipts
