Question

A carnival costs $10.50 to enter plus an additional $3.50 per ticket for rides and food.

Write an algebraic expression to represent the total cost for a visit to the carnival. Let n represent the number of tickets purchased.
​​What is the total cost to visit the fair if you purchase 20 tickets? Explain your reasoning

Answer 1

1.) $10.50 + $3.50n

2.) Replace the variable with the given number. In this case, the given number is 20.

n = 20

$10.50 + $3.50(20)

$10.50 + $70 = $80.50

So, the total cost to visit the fair is $80.50.

Answer 2

Total cost for one who visit the fair and bought 20 tickets is $80. 50

Step-by-step explanation:

The carnival cost to enter is $10 .50 plus an additional $3.50 per ticket for rides and food.

let n = number of ticket purchased

Remember the ticket price is $3.50 per ticket

This means 2 tickets price is $3.50 × 2 = $7 , 3 tickets price = 3.50 × 3 = $10.50 and so on .

The total cost to visit the fair should be

Total cost = Carnival cost for entry + Ticket price(n)

Total cost = $10.50 + $3.50(n)

The total cost for someone who bought 20 tickets

Total cost = $10.50 + $3.50 × 20

Total cost = $10.50 + $70

Total cost = $80. 50

Total cost for one who visit the fair and bought 20 tickets is $80. 50

My reasoning is the fact that the person paid an entry fee of $10.50 plus tickets amounting to 3.50 × 20 = $70.
