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
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
Let's first find the total cost of the skateboard and the helmet. The total cost is $45.50 + $18.25 = $<<45.50+18.25=63.75>>63.75.
We know that he earned one part of the money by mowing lawns. Let's call this portion "x".
We can set up the equation x + (63.75 - x) = 63.75
Combining like terms, we get 63.75 = 63.75
Simplifying, we get 0 = 0.
This equation is true for any value of x.
Therefore, we cannot determine how much Jason earned babysitting.
The answer is D. $42.50
