If you rent 5 DVDs for 5 nights for $5, how much do you expect to pay for 1 DVD for 1 night at this rate?

The **expected value **of the **payment **is $5

What is Proportionality?
When two **quantities **have some **dependence **in their values they can be said proportional to each other.
It can be of two types such as **direct **and indirect .
The direct proportionality means the values of both the quantities are **increasing **or decreasing at the **same **time while the indirect proportionality implies **value **of one quantity is increasing while the other is decreasing .
Given that,
The rent for 5 DVDs for 5 **nights **is $5.
In order to find the rent for 1 night for 1 DVD, **direct **and **indirect proportion **method can be used as follows,
5 DVD for 5 night costs $5.
Then, 5 DVDs for 1 night costs 5 × 5 = $25.
And, 1 DVD for 1 night costs 25/5 = $5.
Hence, the **cost **of 1 DVD for 1 night is $5.

20 cents a night because 5 DVDs per night is 1 dollar, and $1/5 DVDs equals 20 cents each, so 1 DVD is 20 cents a night

Renting 1 DVD for 1 night costs $1 based on the rate provided. This was calculated by taking the total cost of renting 5 DVDs for 5 nights and dividing the cost down. Thus, at this rate, the cost per DVD per night is clear.
