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
One km is about 0.621371 so then you do 400/0.621371 which is 643.738 then you have your answer.400m:643.738km
Multiplying both sides by y+7, we get 2-y=(3y+21)/5 and then by multiplying both sides by 5 we get 10-5y=3y+21. After that, subtract 21 from both sides as well as add 5y to both sides to get -11=8y, so divide by 8 to get -11/8=y
