Sandra wants to rent a car to take a trip and has a budget of $90. There is a fixed rental fee of $30 and a daily fee of $10. Write an inequality that would be used to solve for the maximum number of days for which Sandra can rent the car on her budget.

'D' being 'Maximum amount of days in which Sandra can rent the car' must be equal to 6, as 10*6=60, which is the remainder of Sandra's budget after the 30 dollar fixed fee she must pay.

Answer:

The maximum number of days for which Sandra can rent the car on her budget is 6.

Step-by-step explanation:

Let n be the number of of days for which Sandra can rent the car on her budget.

Fixed rent = $30

Daily fee for 1 day = $10

Daily fee for n days = 10n

So, Total fees = 30+10n

Sandra's budget is $90 .

She cannot spend more than $90.

So, inequality becomes : [tex]30+10n\leq 90[/tex]

[tex]10n\leq 90-30[/tex]

[tex]10n\leq 60[/tex]

[tex]n\leq 6[/tex]

So, the maximum number of days for which Sandra can rent the car on her budget is 6.
