Step-by-step explanation:
there wasn't much context in your question but I believe this is what you were looking for.
The car rental is 38.15 + 12 1/2 per mile or

now, we're assuming she drove that in 1day, thus she's only getting charged 38.15, for 1 day :)
Answer:
a) x= 5 or x= -3
b) x = -4 +
or -4 - ![\sqrt{26}](https://tex.z-dn.net/?f=%5Csqrt%7B26%7D)
Step-by-step explanation:
a)
- 2x - 15 =0
x =
or ![\frac{-(-2) -\sqrt{(-2)^{2} - 4(1)(-15)}}{2(1)}](https://tex.z-dn.net/?f=%5Cfrac%7B-%28-2%29%20-%5Csqrt%7B%28-2%29%5E%7B2%7D%20-%204%281%29%28-15%29%7D%7D%7B2%281%29%7D)
x= 5 or x=-3
b)
+ 8x - 10 =0
x =
or ![\frac{-(8) -\sqrt{(8)^{2} - 4(1)(-10)}}{2(1)}](https://tex.z-dn.net/?f=%5Cfrac%7B-%288%29%20-%5Csqrt%7B%288%29%5E%7B2%7D%20-%204%281%29%28-10%29%7D%7D%7B2%281%29%7D)
x = -4 +
or -4 - ![\sqrt{26}](https://tex.z-dn.net/?f=%5Csqrt%7B26%7D)
