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 \

The total cost of a 700 Mhz computer is:

Quizplus · Accepted Answer

The total cost of a 700 Mhz computer is the cost of a 600 Mhz computer ($900) plus the marginal cost of increasing to 700 Mhz ($100), which equals $1,000.
