Pam bought several cartons of drinks to sell during the track meet. She paid 50 cents per carton. She sold all but 15 for $1 each. at the end of the day she made $22.50. how many cartons did she buy?
Answer provided by our tutors
let x represent the number of cartons Pam bought.
Pam is earning $1 - $0.5 = $0.5 or 50 cents per carton
since she sold all but 15 and made $22.50 we have:
(x - 15)*0.50 = 22.50
by solving we find
x = 60 cartons
