The cancer Society is holding three charity events. They hope the average attendee for the three events will be between 500 and 540, inclusive. The attendance for the first two shows was 480 and 540. What possible attnedence numbers for the third event will allow them to reach their goal? Write and solve am inequality for this situation.
I got x is greater than or equal to 480 AND x is less than or equal to 600.
you need
500*3 <= 480+540+x <= 540*3
1500 <= 1020+x <= 1620
480 <= x <= 500
