Pat bought 5 pounds of apples. How many pounds of pears could he have bought for same amount of money?
1) 1 pound of pears cost $0.5 more that 1 pound of apples
2) 1 pound of pears cost 1.5 times as much as 1 pound of apples
We need a relationship between price of pears and that of apples to solve the question.
1p = 0.5 + 1a
But this relationship is not sufficient to answer because
price of 5 pounds of apples = 5p = 5*0.5 + 5a but we cannot tell for sure about the exact pounds of apples we can buy
1p = 1.5*1a
This relationship is sufficient because
price of 5 pounds of apples = 5p = 5*1.5 *1a= 7.5a
so we know for sure that we can buy 7.5 pounds of apples with the same money.
So, Answer will be B
Hope it helps!
