1 answer

To determine how much Jason earned by babysitting, we need to subtract the amount he earned by lawn mowing from the total cost of the skateboard and helmet.

The skateboard costs $45.50 with tax.
The helmet costs $18.25 with tax.
So, the total cost of the skateboard and helmet is $45.50 + $18.25 = $<<45.50+18.25=63.75>>63.75.

If Jason earned 1/3 of the total cost by mowing lawns, then he earned (1/3) * $63.75 = $<<1/3*63.75=21.25>>21.25 by mowing lawns.

Therefore, Jason earned $63.75 - $21.25 = $<<63.75-21.25=42.50>>42.50 by babysitting. Answer: \boxed{42.50}.
