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.
