Jackson wants to go on a shopping spree, so his mom says she will give him some spending money if he does extra chores. She promises $5 per hour spent on chores.  Jackson spends 2 hours vacuuming, and decides to do this twice. He also spends 0.5 hours washing dishes, and three times as long cleaning the bathroom.  How much spending money has Jackson earned?
Jackson spent a total of 2 * 2 = <<2*2=4>>4 hours vacuuming.
This means he earned 4 * $5 = <<4*5=20>>20 dollars from vacuuming.
He earned 0.5 * $5 = <<0.5*5=2.5>>2.5 dollars from washing dishes.
Cleaning the bathroom took three times as long as the dishes, so he spent 0.5 * 3 = <<0.5*3=1.5>>1.5 hours in the bathroom.
This means he earned 1.5 * $5 = $<<1.5*5=7.5>>7.5 from cleaning the bathroom.
In total, he has earned $20 + $2.5 + $7.5 = $<<20+2.5+7.5=30>>30.
