Question

1 An airport employee checked a group of passengers through security on Thursday. On Friday, she checked three times as many passengers, and on Saturday she processed 5,000 passengers through security. In the 3 days, she processed 15,000 passengers. How many did she process on Friday? 10005000300020007500

Answer 1

Answer:7,500

Explanation

x + 3x + 5,000 = 15,000

4x - 5,000 = 10,000

4x = 10,000

/4

x = 2,500

On friday, she checked 3x, so she processed 2,500 x 3 = 7,500 passengers.
