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}.
