[Question]: Kamil wants to renovate his kitchen at home. For this purpose, he hired two professionals who work for him 6 hours a day for 7 days. What does it cost Kamil to hire these professionals if one of them is paid $15 per hour of work?
[Answer]: Two professionals work together 6 * 2 = 12 hours per day. They work for 7 days, so in total it means 7 * 12 = 84 hours. The cost of hiring these persons is 84 * 15 = $1260.
So the answer is 1260.

[Question]: Tony's dad is very strict about the washing machine and family members are only allowed to wash 50 total ounces of clothing at a time. Tony doesn't want to break the rules, so he weighs his clothes and finds that a pair of socks weighs 2 ounces, underwear weighs 4 ounces, a shirt weighs 5 ounces, shorts weigh 8 ounces, and pants weigh 10 ounces. Tony is washing a pair of pants, 2 shirts, a pair of shorts, and 3 pairs of socks. How many more pairs of underwear can he add to the wash and not break the rule?
[Answer]: He is washing 10 ounces of shirts because 2 x 5 = 10. He is washing 6 ounces of socks because 3 x 2 = 6. He is already washing 34 ounces of clothes because 10 + 10 + 8 + 6 = 34. He can wash 16 more ounces because 50 - 34 = 16. He can wash 4 pairs of underwear because 16 / 4 = 4.
So the answer is 4.
