A shopkeeper sells apples for $7 each and strawberries for $15.00 each. How many apples did the shopkeeper sell today?

(1) The number of apples sold today is 1 more than twice the number of strawberries sold.

(2) Today the shopkeeper received a total of $65 from the sale of both apples and strawberries.

Let A be the number of apples and S the number of strawberries

1. A = 2S + 1

If S = 1, A = 2+1 = 3

If S = 2, A = 4+1 = 5

We cannot find a unique value for the number of apples sold.

(Insuffiicient)2. 7A + 15S = 65

This is only possible when A = 5, S = 2 since both

apples and strawberries are sold

(Sufficient - Option B)
