Bob wants to rent a car for one day. He contacted two companies. Enterprise Rentals charges $100 plus $3 per mile. Hertz Rental charge $8 per mile. After how many will the total cost for both companies be the same ?

20 miles.

Step-by-step explanation:

To solve this problem, we will have to set two expressions representative of Enterprise Rentals & Hertz Rental equal to each other.

Let equal the number of miles.

If Enterprise Rentals charges $100 plus $3 per mile, we can represent this as:

If Hertz Rental charges $8 per mile, we can represent this as:

Set the expressions equal to each other:

Subtract from both sides of the equation:

Divide both sides of the equation by the coefficient of , which is :

Therefore, after 20 miles, the total cost for both companies will be the same.

Check your work by substituting the solved value of (20), into the initial equation:

As the total costs are equal to each other, our answer is correct!

your answer is b ^w^ hope i

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
