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:
[tex]c=4.50 \times n[/tex]
Therefore, the equation that gives the total cost, c, of buying n tickets is [tex]c=4.50 \times n[/tex]
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:
[tex]n=\frac{36}{4.5}[/tex]
[tex]=8[/tex]
Now if one more ticket is purchased, there will be 8 +1 =9 tickets.
Therefore, the cost of 9 tickets is:
[tex]c=4.50 \times 9 = 40.5[/tex]
Hence the total cost if one more ticket is purchased is $40.5
