100y x 7x = 700

simple equation. 
y= cost of rent per day
x = days
700= total

the way you typed this confused the hell out of me. so let me know if i didnt get something right.

Answer 2

Answer:

$]\text{Total cost} = \text{Cost of renting a car per day}\times \text{Number of days for which the car is rented.}$

Step-by-step explanation:

We are given the following information in the question:

In order to answer his question we have to make the following assumptions:

Let z be the cost of renting the car for one day.

We are given that y is the cost of renting the cars for x days.

$\text{Total cost} = \text{Cost of renting a car per day}\times \text{Number of days for which the car is rented.}$

Thus, total cost y for renting car for x days at z cost of renting per day =

$y(\text{Total Cost}) = x(\text{Number of days})\times (\text{Cost of renting per day})\\y =x\times z$

The above equation is the required equation for total cost of renting a car for x days.
