Afair charges $7.25 for admission and $5.50 for a ride pass. ten friends visited the fair. not all of the friends purchased ride passes. if their total cost was $105.50, how many friends purchased ride passes? tell me pls you

You take
7.25 (10)+5.5p=105.5
72.5+5.5p=105.5
To make the equation easier multiply the whole equation by ten like this
(72.5+5.5p=105.5)10 that equals
725+55p=1055
Then subtract 725 to both sides
725+55p=1055
-725 -725

55p=330
Then divide by 55 on both sides and that equals 6 so 6 people bought tickets
