Answer:
If they spent the same amount of money, then an apple is $2 less then an orange.
Explanation:
So, we already know that Lu has 12 apples and oranges. We also know the ratio: 3 apples:2 oranges.
So, in order to see the cost of one apple and one orange, we need to divide the number 12 by these numbers.
12 ÷ 3 = $4 per apple
12 ÷ 2 = $6 per orange
Therefore, if they spent the same amount of money, (which can only give them 3 apples for $12, or 2 oranges for $12), then an apple is $2 less then an orange.
