Frank ordered playoff tickets for himself and three friends.There is a $7 service fee per ticket and a additional shipping cost of $12 for the entire thing

Question

First question: write an algebraic expression to represent  the situation 

 

Second question:write an algebraic  expression to represent the ticket cost per person

Answer 1

let x = cost per ticket

 

he bought a ticket for himself and three friends = 4 tickets

the service fee = $7/ticket x 4 tickets

the shipping fee is $12

 

1. Total cost = 4x +($7/t)4t + $12, which gives us 4x + $40

 

2. x = (Total cost - $40)/4
