You and some friends are to the museum. each ticket cost $4.50

Solution: Part A

If n is the number of tickets purchased, write an equation that gives the total cost, c, of buying n tickets

We know that a ticket costs $4.50

Now if n tickets are purchased, the total cost is given below:

Therefore, the equation that gives the total cost, c, of buying n tickets is

Part B:

Suppose the total cost for n tickets is $36. What is the total cost if one more ticket is purchased?

The number of tickets purchased, if the total cost = $36 is:

Now if one more ticket is purchased, there will be 8 +1 =9 tickets.

Therefore, the cost of 9 tickets is:

Hence the total cost if one more ticket is purchased is $40.5

99
