Answer:
two tires for $35 -------------------------$70 total
three rims for $75--------------------------- $225
five headlights for $ 4.00 ----------------$20
Emma spends ($225+$70+$20) =$315
Now Emma sells them for 2 tires for $65 =130
3 rims for $136 = $408
5 headlights for $15 = $75
total money Emma makes = $613.
the profit is $613- $315= $298
the profit is $298

- Outer radius, in inches.
If we know that 
, 
and 
, then the area wiped by the wiper blade is:
![A = \frac{130\pi}{360} \cdot [(25\,in)^{2}-(14\,in)^{2}]](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B130%5Cpi%7D%7B360%7D%20%5Ccdot%20%5B%2825%5C%2Cin%29%5E%7B2%7D-%2814%5C%2Cin%29%5E%7B2%7D%5D)
