A large pool equipment set costs $1,042. A small pool equipment set costs $907. How much does it cost to buy 3 large pool equipment sets?
When you are multiplying, you are actually doing repeated addition. So, if a problem asks how much 5 or 7 or 9 of a particular item would be, it's just like you had added that cost five, seven, or nine times.
Answer and Explanation:
If a large pool equipment set costs $1,042, three large pool equipment sets would cost $3,126. This is because $1,042 * 3 equals $3,126. You could also do this by repeated addition: $1,042 + $1,042 + $1,042 equals $3,126. The inclusion of the price of the small pool equipment set doesn't make any difference to this problem. Sometimes extraneous or distracting information is put into math problems. You need to ignore the information that isn't needed to answer the given question.
