The following table shows the relationship between the speed of a computer's CPU and the benefits and costs.Assume that all other features of the computer are the same,i.e. ,CPU speed is the only source of variation. $$\begin{array} { | l | l | l | l | l | }
\hline \text { CPU Mhz } & \text { Total Benefit } & \text { Marginal Benefit } & \text { Total Cost } & \text { Marginal Cost } \
\hline 600 & \$ 1,000 & & \$ 900 & \
\hline 700 & \$ 1,500 & & & \$ 100 \

\end{array}$$
The total benefit of an 800 Mhz computer is:

Quizplus · Accepted Answer

The total benefit at 800 MHz can be calculated by adding the marginal benefit of $400 to the total benefit at 700 MHz, which is $1,500, resulting in $1,900.
