Question

Part A

840 students at Junior High North are either iphone users or other phone users. Of these
students, 25 less than 4 times as many have iphones than another phone type. How many
students use an Iphone? How many students use another phone?

Answer 1

other phones = 173

iphones = 667

Explanation:

x = # of students with other phones

4x - 25 = # of students with iPhones

x + (4x - 25) = 840

5x - 25 = 840

5x = 840 + 25 = 865

x = 865/5 = 173

4(173) - 25 = 667
