Jason is saving up for a skateboard and helmet. The skateboard is $45.50 with tax and the helmet is $18.25 with tax. He earned 1/3 of the money by mowing Lawrence and the rest by babysitting. How much did Jason earn babysitting

Answer 1

The total cost of the skateboard and helmet is $45.50 + $18.25 = $<<45.50+18.25=63.75>>63.75.
Jason earned 1/3 * $63.75 = $<<1/3*63.75=21.25>>21.25 mowing Lawrence.
Therefore, he earned $63.75 - $21.25 = $<<63.75-21.25=42.5>>42.5 babysitting. Answer: \boxed{42.5}.
