Total amount spend at fair = $30

To find:

The equation that represents the problem.

Solution:

Let the number of activities be .

Additional fee for 1 activity =

Additional fee for x activity =

Total fee = Entrance fee + Additional fee for x activity

               =

It is given that Kevin has at most $30 to spend at the fair. So, total fee must be equal to $30.

Therefore, the require equation is .

Note: The inequality for the given problem is .

i think the correct option is the second option.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
