Answer:
Kay sold 67 cell phones and Allen sold 50 cell phones.
Step-by-step explanation:
Let k = # cell phones Kay sold and a = # cell phones Allen sold.
k + a = 117
k = 17 + a
So:
(17 + a) + a = 117
2a = 100
a = 50
Plug this back into 2nd equation:
k = 17 + a
k = 17 + 50
k = 67
Kay sold 67 cell phones and Allen sold 50 cell phones.
