Answer:
Step-by-step explanation:
First, we write the rental cost with each company:
Company A ![Pa = 100 + 0.2*m](https://tex.z-dn.net/?f=Pa%20%3D%20100%20%2B%200.2%2Am)
Company B ![Pb = 60 + 0.7*m](https://tex.z-dn.net/?f=Pb%20%3D%2060%20%2B%200.7%2Am)
Where m: miles travelled
Now, we need to find "number of miles in a day at which the rental costs for Company A and Company B are the same". This means Pa = Pb. Then:
![100 + 0.2*m = 60 + 0.7*m](https://tex.z-dn.net/?f=100%20%2B%200.2%2Am%20%3D%2060%20%2B%200.7%2Am)
Solving the equation for m by taking 0.2m and 60 on both sides:
![100 + 0.2*m - 0.2*m - 60 = 60 + 0.7*m - 0.2*m - 60](https://tex.z-dn.net/?f=100%20%2B%200.2%2Am%20-%200.2%2Am%20-%2060%20%3D%2060%20%2B%200.7%2Am%20-%200.2%2Am%20-%2060)
![40 = 0.5*m](https://tex.z-dn.net/?f=%2040%20%3D%200.5%2Am)
Finally, dividing 0.5 on both sides:
![m = 80](https://tex.z-dn.net/?f=%20m%20%3D%2080)

Answer:
![\displaystyle \frac{7\frac{3}{4}}{\frac{1}{4}}=31](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B7%5Cfrac%7B3%7D%7B4%7D%7D%7B%5Cfrac%7B1%7D%7B4%7D%7D%3D31)
Step-by-step explanation:
<u>Fractions</u>
We are given the expression:
![\displaystyle \frac{7\frac{3}{4}}{\frac{1}{4}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B7%5Cfrac%7B3%7D%7B4%7D%7D%7B%5Cfrac%7B1%7D%7B4%7D%7D)
We'll find an equivalent expression that results when simplifying the given fraction.
The numerator is a mixed fraction, which we'll convert into an improper fraction as follows:
![7\frac{3}{4}=7+\frac{3}{4}=\frac{4*7+3}{4}=\frac{31}{4}](https://tex.z-dn.net/?f=7%5Cfrac%7B3%7D%7B4%7D%3D7%2B%5Cfrac%7B3%7D%7B4%7D%3D%5Cfrac%7B4%2A7%2B3%7D%7B4%7D%3D%5Cfrac%7B31%7D%7B4%7D)
Now it follows:
![\displaystyle \frac{7\frac{3}{4}}{\frac{1}{4}}=\frac{\frac{31}{4}}{\frac{1}{4}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B7%5Cfrac%7B3%7D%7B4%7D%7D%7B%5Cfrac%7B1%7D%7B4%7D%7D%3D%5Cfrac%7B%5Cfrac%7B31%7D%7B4%7D%7D%7B%5Cfrac%7B1%7D%7B4%7D%7D)
Instead of dividing fraction, we multiply by the reciprocal of the denominator:
![\displaystyle \frac{7\frac{3}{4}}{\frac{1}{4}}=\frac{31}{4}\cdot \frac{4}{1}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B7%5Cfrac%7B3%7D%7B4%7D%7D%7B%5Cfrac%7B1%7D%7B4%7D%7D%3D%5Cfrac%7B31%7D%7B4%7D%5Ccdot%20%5Cfrac%7B4%7D%7B1%7D)
Simplifying:
![\mathbf{\displaystyle \frac{7\frac{3}{4}}{\frac{1}{4}}=31}](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Cdisplaystyle%20%5Cfrac%7B7%5Cfrac%7B3%7D%7B4%7D%7D%7B%5Cfrac%7B1%7D%7B4%7D%7D%3D31%7D)
