Question

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

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

I think the expression would be 10.50(3.50)=n? I honestly don't know though!

Answer 1

a: 10.50+3.50n

b: $80.50, if you bougt one ticket for 3.50, 20 tickets would end up in $70

plus the 10.50 entrance fee

Answer 2

You were close. The answer would be N = $3.50x + $10.50

Then answer 2 is $80.50
