To determine how much Jason earned by babysitting, we first need to calculate the total cost of the skateboard and helmet.
- Cost of skateboard: $45.50
- Cost of helmet: $18.25
Total cost = Cost of skateboard + Cost of helmet
Total cost = $45.50 + $18.25 = $63.75
Now we need to find out how much of that total Jason earned by babysitting, knowing that he earned some of it by mowing lawns.
However, the problem does not provide the exact amounts earned from mowing lawns. Without that specific information, we can't directly calculate how much he earned from babysitting (unless more information is given).
If we assume he earned a certain total amount (for example, one of the options provided), we could then subtract the amount he earned mowing lawns from that total to find out how much he earned from babysitting.
If you can provide how much he made from mowing lawns or clarify, I would be happy to assist further! If not, it's not possible to determine precisely how much Jason earned babysitting with the information provided.
