Answer 1

To find out how much Jason earned babysitting, we first need to calculate the total cost of the skateboard and helmet.

1. Total Cost:

   • Skateboard: $45.50
   • Helmet: $18.25

   \[ \text{Total Cost} = \text{Skateboard} + \text{Helmet} = 45.50 + 18.25 = 63.75 \]

2. Amount Earned from Mowing Lawns: Jason earned \( \frac{1}{3} \) of the total amount through mowing lawns.

   \[ \text{Amount from Mowing Lawns} = \frac{1}{3} \times 63.75 \]

   To calculate that:

   \[ \frac{1}{3} \times 63.75 = 21.25 \]

3. Amount Earned Babysitting: The rest of the money was earned through babysitting, which is \( \frac{2}{3} \) of the total amount.

   \[ \text{Amount from Babysitting} = \text{Total Cost} - \text{Amount from Mowing Lawns} \] \[ \text{Amount from Babysitting} = 63.75 - 21.25 = 42.50 \]

Thus, Jason earned $42.50 babysitting.
