720 .
Explanation
Understanding the Problem The problem states that a merchant bought 30 dozen pairs of gloves. We need to find the total number of individual gloves the merchant bought.
Calculating the Number of Pairs First, we need to determine how many pairs of gloves the merchant bought. Since there are 12 items in a dozen, 30 dozen pairs of gloves is equal to 30 × 12 pairs.
Pairs of Gloves 30 × 12 = 360 pairs of gloves.
Calculating the Number of Individual Gloves Since each pair of gloves contains 2 individual gloves, we multiply the number of pairs by 2 to find the total number of individual gloves.
Individual Gloves 360 × 2 = 720 individual gloves.
Final Answer Therefore, the merchant bought a total of 720 individual gloves.
Examples
Imagine you are buying party favors for a large event. If you decide to buy 30 boxes of party favors, where each box contains a dozen pairs of novelty glasses, you would need to calculate the total number of individual glasses to ensure every guest gets one. This problem is similar; by calculating the total number of individual items (gloves or glasses), you can plan effectively for your needs.
The merchant bought a total of 720 individual gloves by calculating 30 dozen pairs, which equals 360 pairs, and multiplying that by 2. The chosen answer is A) 720.
