Question

before the sale, the store had 100 pairs of sandals in stock. after selling some, they notice that 3/5 of the sandals they have left are blue. if the store had 39 pairs of blue sandals, how many pairs of sandals (of any color) have they sold?

[AI-generated answer — Bot GPT 3.5]

If 3/5 of the remaining sandals are blue, then 2/5 must be of other colors. Since the store had 39 pairs of blue sandals left, we can set up the following equation:

2/5 * remaining sandals = 39
2/5 * remaining sandals = 39
remaining sandals = 39 * 5 / 2 = 97.5

Since you can't have half a pair of sandals, we can deduce that the store actually had 98 pairs of sandals left.
So, if they had 100 pairs originally and were left with 98 pairs, they must have sold 100 - 98 = 2 pairs of sandals.
