Question

A group of friends decided to go out of town to a championship football game. The group pays $185 per ticket plus one time convenience fee of $15. They also each pay $27 to ride a tour bus to the game. If the group spent $2,771 In total, how many friends are in the group ?

Answer 1

The number of friends in the group is 13

What is the appropriate function for $2771 spent in total?

The total cost function would consider all expenses, the one-time convenience fee of $15, the ticket cost per person  multiplied by the number of persons in the group and the fee for ride of $27 multiplied by number of friends going together

Let x represents the number of friends  going to the championship

Total cost=15+185x+27x

total cost=2771

2771=15+185x+27x

2771-15=212x

2756=212x

x=2756/212

x=13
