Brett paid $229 for 8 tickets to a baseball game, which includes the $13 service fee applied to every order. How much will Brett

nataly862011 [7]

Answer:

$418

Step-by-step explanation:

So first we need to find how much a single ticket will cost.

Subtract the service fee to get how much it cost for 8 tickets.

229-13=216

Then divide that number by 8 to find how much a single ticket costs.

216÷8=27

1 ticket costs $27.

Multiply that by 15 to get how much 15 tickets cost.

27×15=405

Then add back the service fee.

405+13=418
