Inequality:
3d<=25
Divide each term in the inequality by 3.
(3d)/(3)<=(25)/(3)
Simplify the left-hand side of the inequality by canceling the common factors.
d<=(25)/(3)
(25)/(3)
The approximate value of (25)/(3) is 8.333333.
8.333333
Answer= 8 days
To check:
If d=8;
3(8)<=25
Multiply 3 by each term inside the parentheses.
24<=25
Since 24<=25, the equation will always be true.
Always True

If d is the number of days rented, then

However, if d is a whole number, then because if d is 9, the rental cost is $27.
