Solve the problem.Suppose that the speed of a car, measured in miles per hour (mph), is monitored for some short period of time after the driver applies the brakes. The following table and graph relate the speed of the car to the amount of time, measured in seconds (sec), elapsed from the moment that the brakes are applied. What is happening to the speed of the car during this time frame? In which of the time intervals does the speed change the most?
A. With increasing elapsed time, the speed increases. The speed changes most during the time interval from 8 seconds to 10 seconds.
B. With increasing elapsed time, the speed increases. The speed changes most during the time interval from 2 seconds to 4 seconds.
C. With increasing elapsed time, the speed decreases. The speed changes most during the time interval from 8 seconds to 10 seconds.
D. With increasing elapsed time, the speed decreases. The speed changes most during the time interval from 2 seconds to 4 seconds.

Solve.The amount of simple interest earned on an investment over a fixed amount of time is jointly proportional to the principle invested and the interest rate. A principle investment of $2200.00 with an interest rate of 8% earned $176.00 in simple interest. Find the amount of simple interest earned if the principle is $4900.00 and the interest rate is 4%.
A. $88.00 B. $392.00 C. $196.00 D. $19,600.00
