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?
A.
$19.13
B.
$21.25
C.
$30.33
D.
$42.50
The total cost of the skateboard and helmet is $45.50 + $18.25 = $<<45.50+18.25=63.75>>63.75.
To find out how much Jason earned babysitting, we need to subtract the amount he earned from mowing lawns.
If 1/3 of the total is from mowing lawns, then 2/3 is from babysitting.
To find how much Jason earned babysitting, we can multiply the total by 2/3, which is $63.75 * 2/3 = $<<63.75*2/3=42.50>>42.50.
Therefore, Jason earned $42.50 babysitting. The answer is D. $42.50.
