Question

Kay and Allen sell cell phones. Last month Kay sold 17 more cell phones than Allen. Together they both sold 117 cell phones. How many phones did each of them sell individually. Show the equation you used to determine the answers.

Answer 1

Explanation:

K = A + 17

K + A = 117

A + 17 + A = 117

2A + 17 = 117

2A = 117 - 17

2A = 100

A = 100/2

A = 50 <=== what Allen sold

K + A = 117

K + 50 = 117

K = 117 - 50

K = 67 <==== what Kay sold
