Question

1/3
of the money by mowing lawns and the rest by babysitting. How much did Jason earn babysitting?

Answer 1

First, we need to find the total cost of the skateboard and helmet.

1. Total Cost: $$\text{Total Cost}=\text{Cost of Skateboard}+\text{Cost of Helmet}$$ $$\text{Total Cost}=45.50+18.25=63.75$$

2. Earnings from Mowing Lawns: Jason earned $\frac{1}{3}$ of the total amount needed for the skateboard and helmet by mowing lawns. $$\text{Earnings from Mowing Lawns}=\frac{1}{3}\times 63.75$$ $$\text{Earnings from Mowing Lawns}=21.25$$

3. Earnings from Babysitting: The rest of the money Jason earned is from babysitting, which is $\frac{2}{3}$ of the total. Thus: $$\text{Earnings from Babysitting}=\text{Total Cost}-\text{Earnings from Mowing Lawns}$$ $$\text{Earnings from Babysitting}=63.75-21.25=42.50$$

Therefore, Jason earned $42.50 babysitting.
