8. GENERAL: Electrical Consumption – On a hot summer afternoon, York College’s electricity consumption is – 3t t + 10 units per hour, where t is the number of hours after noon (0 ≤ t ≤ 6). Find the total consumption of electricity between the hours of 1 and 5 p.m. The total consumption of electricity will be 132 units.

9. BUSINESS: Cost - A company’s marginal cost function is MC (x) = 6e -.02x, where x is the number of units. Find the total cost of the first hundred units. The total cost of the first hundred units will be $

10. BUSINESS: Tin Consumption – World consumption of tine is running at the rate of 0.26 e.01t million metric tons per year, where t is measured in years and t = 0 corresponds to the beginning of find the total consumption of tine from the beginning of 2008 to the beginning of The total consumption of tin from 2008 to 2018 will be 2.73 million metric tons..

11. BEHAVIORAL SCIENCE: Learning – A student can memorize words at the rate of 6 e -t/5 words per minute after t minutes. Find the total number of words the student can memorize in the first 10 minutes. The student can memorize about 26 words in the first 10 minutes.

12. BIOMEDICAL: Drug Absorption – An oral medicine is absorbed in the blood stream at the rate of 6 e t milligrams per minute. Where t is the number of minutes since the drug has been administered. Find the total amount of medication absorbed within the first 30 minutes. About 105 milligrams of drug will be absorbed in the first 30 minutes.

13. BUSINESS: Sales – A car dealer predicts that new cars will sell at the rate of 8xe - 0.1x sales per week x. Find the total sales in the first half year. About 586 cars will be sold in the first half year.
