I would love to understand how to solve this problem: Jason was told he could earn $3.00 for doing his laundry,  $1.50 for cleaning his room, $0.75 for taking the trash to the curb each week and $0.50 for emptying the dishwasher.  In a two week period, Jason emptied the dishwasher 6 times, did his laundry once, took the trash out twice and cleaned his room once.  How much money did Jason earn?
Can you explain?
