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.
30x + 10 ≤ 90
30 + 10x ≤ 90
30x + 10 ≥ 90
30 + 10x ≥ 90

30 + 10x ≤ 90

step-by-step explanation:

costs:   fixed fee of 30

          daily fee of 10 * number of days

total cost

30+10x   where x is the number of days

this must be less than or equal to 90   since that is how much her budget is

90 ≥ 30+10x

30 + 10x ≤ 90

step-by-step explanation:

the inequality 30 + 10x ≤ 90 shows what would be used to solve for the maximum number of days for which sandra can rent the car on her budget.

x = how many days

< or = to 90

therefore, 30 + 10x ≤ 90
