There are given that the trend line.

The trend line is,

[tex]y=101x+207.85[/tex]

Now,

Where x is the speed of the processor.

So, speed of the processor is given that,

[tex]x=2.5[/tex]

Then,

For the amount of price,

Put the value of x in given equation,

So,

[tex]\begin{gathered} Y=101x+207.85 \\ Y=101\times2.5+207.85 \\ Y=252.5+207.85 \\ Y=460.35 \end{gathered}[/tex]
