If I was to be holding two drill bits: one is 3/8 and one is 11/32. I want to first drill a hole using the smaller of the two bits. To decide which is smaller, I person expands 3/8 to 32nds. What is the expanded fraction?

I take my truck in for basic service. The service agent says a few extra repairs are also needed, so I add the cost of those repairs in my head, rounding to the nearest $10. The costs are as follows:

Wheel alignment: $110

Transmission fluid flush: $75

Cabin air filter: $23

What is my total estimate for the repairs?

Note: 4 or less: round down, 5 or more: round up. For example, 14 becomes 10, while 15 becomes 20

I am planning a party at a party hall. The party hall offers a meal option for $50 per person and that includes the hall rental for free. The hall-only rental option is $1,150, but that option allows an external caterer to provide the meal. My external caterer charges $27.50 per person. If he plans to invite 50 people, which is the cheaper option?

If I buy 32 one-liter bottles of soda bottles for a large company party. The store clerk offers cardboard carrying cases for the bottles and each case holds 8 bottles. Assuming each case would be filled, and I will not be carrying any loose bottles outside of a case, how many cases are needed?
