Every day, Bob logs 10 hours of work in his office. If he works for five days a week, calculate the total number of hours he logs in a month.
Let's think: In a week, working 10 hours a day, Bob logs 10 * 5 = 50 hours. After a month with 4 weeks, Bob logs 4 * 50 = 200 hours for his office working hours.. The answer is: 200.

Jim has a pail with rocks in it. The average weight of a rock is 1.5 pounds. A local rock collector agrees to pay him $4 for every pound of rocks. If he makes $60 off the sale, how many rocks were in the bucket?
Let's think: There were 15 pounds of rocks in the bucket because 60 / 4 = 15. There were 10 rocks in the bucket because 15 / 1.5 = 10.. The answer is: 10.

Ashley had a birthday party and invited 20 of her friends, telling them to each invite one more person to attend the party. If half the number of the invited guests each came with one more person, what's the total number of people at the party, including Ashley?
Let's think: If she invited 20 friends, then the number of friends who came with one more person is 1 / 2 * 20 = 10. If the 10 friends came with 10 more people, the total number of guests becomes 20 + 10 = 30 guests. If you add Ashley, the total number of people in the party is 30 + 1 = 31 people.. The answer is: 31.

There are 180 days in a school year. A senior can skip their final exams if they miss 5% or less of the school year. Hazel has missed 6 days of school due to illness. How many more days can she miss and still not have to take her exams?
Let's think:
There are 180 days in the school year and she can miss up to 5% so that’s 180 * .05 = 9 days. Hazel has been sick 6 days already and she can only miss 9 days or less so she can miss 9 - 6 = 3 more days.. The answer is: 3.
