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

Because it says $1.50 EACH so to get the answer you’ll need to multiply $1.50 with each avocado she buys to get the total cost
I mean, I don't know how to explain a generic way to solve this. Ask me about the specific train of thought if you are interested:
7 * 18 + 45 / 3 - 2 = 139
