olga buys tickets to a concert. she pays $27.75 for each ticket plus a handling fee of $5.50 for the order. the total cost is $144.25. how many tickets, n, did olga buy?

First: subtract from the total cost a handling fee of $5.50 for the order:

$144.25 - $5.50 = $138.75

Next: divide it by the price of one ticket:

$138.75 : $27.75 = 5

Answer: Olga buy 5 tickets.

Other method:

t - number of tickets

The equation

27.75 · t + 5.50 = 144.25 |-5.50

27.75t = 138.75 |:27.75

t = 5

Dang those concert tickets are a good price haha.

first you add the ticket price and the handling fee

27.75 + 5.50 = 33.25 for one ticket

now you divide

$144.25 divided by the cost of one ticket

144.25 / 33.25 = 5
