Linda is buying boxes of ice cream sandwiches for her class party. She has to decide how many boxes she should purchase. A formula for this scenario is: Z=ax/y where z=number of boxes, a= number of bars each student will eat, x= number of students at the party, y= number of ice cream bars per box.
Linda has 15 students in her class, and she wants each student to have 2 ice cream sandwiches. If there are 10 sandwiches in a box, how many boxes should Linda buy?
