Answer:

Kay sold 67; Allen sold 50

Step-by-step explanation:

Let "a" represent the number of phones that Allen sold.

a + (a+17) = 117 . . . equation used to find the answer

2a = 100 . . . . . . . . subtract 17, collect terms

a = 50 . . . . . . . . . . divide by 2; the number Allen sold

a+17 = 67 . . . . . . . . Kay sold 17 more than Allen
