Answer:
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!
Answer: OPTION C.
Step-by-step explanation:
By definition, equivalent expressions have the same value but they look different.
You can obtain an equivalent expression by manipulating it algebraically.
In this case, given the following expression:
You can find and equivalent expression by combining or adding the like terms (You need to remember that the like terms are those terms that have the same variable with the same exponent).
So, you can identify that like terms are:
and
Then, you can combine them by adding their coefficients (The coefficients are the numbers in front of the variable).
Therefore, you get the following equivalent expression:
