concert tickets are for sale online. there is a handline fee of $3.50 added to the cost of every tickets. if you uy 7 tickets and the total comes to $385 what is the cost of one ticket before the handling fee is added?
the answer is $51.50 but i got 51 i dun know why i solve it like this (below)
7x+3.50= 385
7x=381.5
x=54.5
54.53.50 = i got 51

The equation is
7x = 385  7(3.50)
7x = 385  24.50
7x = 360.50
x = 51.5
EACH ticket has a 3.50 service fee

Well, you arrived at the same answer, but the equation is not correct for the problem.
Your equation doesn't make sense.
Where did you get 380?
380/7 = 54.29 not 55, even rounded it would be 54 or 54.30 not 55.
And, it is 3.50 fee/ticket.
You can't randomly subtract 3.50 from your total just to arrive at the correct answer.
What's wrong with doing the equation the correct way?
