Answer:
Equation : $83.50x = Cost of the tickets
(where x = number of tickets)
Cost of 6 tickets : $501
Explanation:
I'm not sure if this is the way they want you to do it, but what I did is :
1) Solve a proportion to figure out the cost of 1 ticket
5/417.50 = 1/x
5x = 417.50(1)
5x/5 = 417.50/5
x = 83.50
So, the cost of 1 ticket is $83.50
2) Create an equation
If x equals the number of tickets :
83.50x = Cost of the tickets
3) Solve for 6 tickets
83.50(6) = Cost of the tickets
501 = Cost of the tickets
Substitute x for the number of tickets, which is 6 and you'll get $501 :)
