For a school play the teacher asked the class to set up chairs in 20 rows with 25 chairs in each row. after setting up all the chairs, they were 5 chairs short. how many chairs did the class set up?

The class set up 495 chairs.

Step-by-step explanation:

Hi, to answer this question, first we have to multiply the number of rows (20) by the number of chairs in each row (25).

Mathematically speaking:

20x25= 500

Since they were 5 chairs short, we have to subtract 5 to the previous result.

500-5 = 495

The class set up 495 chairs.
