Depending if you mean (7-2)/3 or 7-(2/3)
Let flat rental fee be F
And per mile charge be M
We know that Bob drove 138 miles and was charged $112.96
And Carl drove 209 miles and was charged $142.78.
⇒ F + 138×M = 112.96 .............. (i)
And F + 209×M = 142.78 ................ (ii)
Subtracting (i) from (ii)
71×M = 29.82
⇒ M = 0.42
Substituting value of M in (i)
⇒ F + 138×0.42 = 112.96
⇒ F + 57.96 = 112.96
⇒ F = 55
So the fixed charge was $55 and the per mile charge was $0.42

Step-by-step explanation:
maths
To solve the area of a cylinder, you need to do steps.
Calculate volume of a cylinder: V = πr2h.
...
Calculate the lateral surface area of a cylinder (just the curved outside)**: L = 2πrh.
...
Calculate the top and bottom surface area of a cylinder (2 circles): T = B = πr. ...
Total surface area of a closed cylinder is:
439.82 square inches
