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 lawns and the rest by babysitting. How much did Jason earn babysitting

Answer 1

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

The cost of the skateboard is:
$$\$45.50$$ The cost of the helmet is:
$$\$18.25$$

Now, let's calculate the total cost:
$$\text{Total cost}=45.50+18.25=63.75$$

Next, we know that Jason earned $\frac{1}{3}$ of the total cost by mowing lawns. We can find that amount:
$$\text{Amount earned by mowing lawns}=\frac{1}{3}\times 63.75=\frac{63.75}{3}=21.25$$

To find out how much Jason earned by babysitting, we subtract the amount earned by mowing lawns from the total cost:
$$\text{Amount earned by babysitting}=63.75-21.25=42.50$$

Thus, Jason earned $42.50 babysitting.
