The Solution:
Given:
Let the yearly cost of one computer be x.
And that of the other computer be 2x.
The total cost of renting the two computers = $2700
[tex]\begin{gathered} x+2x=2700 \\ 3x=2700 \\ x=\frac{2700}{3}=900=\text{ \$}900 \end{gathered}[/tex]
So, the most expensive one will cost:
[tex]Most\text{ expensive computer}=2x=2\times900=\text{\$}1800[/tex]Therefore, the correct answer is [option B]
