Answer: the number of tickets that Olga bought is 5
Explanation:
Let x represent the number of tickets that Olga bought.
Olga buys tickets to a concert. She pays $27.75 for each ticket, plus handling fee of $5.50 for The order. This means that the total amount that Olga paid for x tickets would be
27.75x + 5.5
If the total cost is $144.25, the equation representing the situation would be expressed as
27.75x + 5.5 = 144.25
27.75x = 144.25 - 5.5
27.75x = 138.75
x = 138.75/27.75
x = 5
