A large group of employees rented four vehicles on a business trip. Each vehicle was full of fuel when it was received and must be full of fuel when it is returned. The two mini vans each got 22 miles per gallon and the two sport sedans got 30 miles per gallon. Each vehicle was driven a total of 200 miles. If fuel costs are $3.20 per gallon, how much will it cost to fill up all four vehicles prior to turning them in? $96.48 $100.84 $104.08 $108.84 In the first month a manufacturing plant produced the following number of parts over four weeks: 10200, 9630, 12632 and 10850. The second month produced 12423, 8423, 14632 and 8150. Which month had the higher weekly average over the four weeks, and by how many parts? first month, 85 first month, 79 second month, 102 second month, 79

It will cost $100.84 to fill up all four vehicles, and the second month had the higher weekly average over the four weeks by 102 parts.

For the first part of the question regarding the fuel costs, the total mileage for the two mini vans (22 miles per gallon) and the two sport sedans (30 miles per gallon) is 200 miles each. Combining these, the total distance traveled is 800 miles. With fuel costs at $3.20 per gallon, the total cost to fill up all four vehicles is calculated as (800 miles / combined miles per gallon) * cost per gallon, resulting in $100.84.

For the second part of the question, comparing the weekly averages of produced parts in the first and second months, the weekly averages are calculated by dividing the total parts produced in each month by the number of weeks (four weeks in both cases). The first month's weekly average is (10200 + 9630 + 12632 + 10850) / 4 = 10828 parts, and the second month's weekly average is (12423 + 8423 + 14632 + 8150) / 4 = 10707 parts. Therefore, the first month had the higher weekly average, and the difference is 10828 - 10707 = 121 parts. The correct answer is the "first month, 121."
