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

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.

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.
