Question

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

Answer 1

Solution: Part A

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

Answer:

We know that a ticket costs $4.50

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

`c=4.50 * n`

Therefore, the equation that gives the total cost, c, of buying n tickets is
`c=4.50 * n`

Part B:

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

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

`n=(36)/(4.5)`

`=8`

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

Therefore, the cost of 9 tickets is:

`c=4.50 * 9 = 40.5`

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