The mean is computed as follows:

$\operatorname{mean}=\frac{\text{ sum of the terms}}{\text{ number of terms}}$

In this case, the number of terms is the number of computers.

To find the sum of the terms, we need to multiply the number of computers by each price and add them, that is,

$\begin{gathered} \operatorname{mean}=(17\cdot2050+18\cdot1050+14\cdot1000)/(17+18+14) \\ \operatorname{mean}=(34850+18900+14000)/(49) \\ \operatorname{mean}=(67750)/(49) \\ \operatorname{mean}=1383\text{ \$} \end{gathered}$
