Here are two stories:
The initial freshman class at a college is 10% smaller than last year’s class. But then during the first week of classes, 20 more students enroll. There are then 830 students in the freshman class.
A store reduces the price of a computer by $20. Then during a 10% off sale, a customer pays $830.
Here are two equations:
0.9x + 20 = 830
0.9(x - 20) = 830

Decide which equation represents each story.

Draggable item		Corresponding Item
0.9x + 20 = 830		The freshman class
0.9(x - 20) = 830		The computer
