Lily Quinn makes $12.50 an hour. She works 4 hours on Monday, 6 hours on Tuesday, 9 hours on Wednesday, 3 hours on Thursday, and 7 hours on Friday. What is her gross pay?

To find Lily Quinn's gross pay, we need to calculate the total amount of money she earns for each day and then add them up.

First, let's calculate the earning for each day:

On Monday, Lily works 4 hours, so she earns 4 * $12.50 = $<<4*12.5=50>>50.
On Tuesday, Lily works 6 hours, so she earns 6 * $12.50 = $<<6*12.5=75>>75.
On Wednesday, Lily works 9 hours, so she earns 9 * $12.50 = $<<9*12.5=112.5>>112.5.
On Thursday, Lily works 3 hours, so she earns 3 * $12.50 = $<<3*12.5=37.5>>37.5.
On Friday, Lily works 7 hours, so she earns 7 * $12.50 = $<<7*12.5=87.5>>87.5.

To find her gross pay, we add up the earnings for each day:

Gross pay = $50 + $75 + $112.5 + $37.5 + $87.5 = $<<50+75+112.5+37.5+87.5=362.5>>362.5.

Therefore, Lily Quinn's gross pay is $362.5.

Multiply her total hours by $12.50.
