Twenty students from a soccer team want to attend a match. The ticket price is $25 for each student, and the transportation and meals for everyone will cost $500. To pay for the trip, the students design jerseys to sell for a profit of $20 per jersey. How many jerseys must the students sell so that there will be enough money to pay for the entire cost of the trip?
you multiply the 25$ and $500 ($25 x 20)+($500 x 20) by the number of students, and then add them together. after that, you multiply it by the $20 ($10,500/$20 = 525) for the jerseys to get 525 jerseys
