Question

Let me know if you need a better picture it’s bad quality but readable

Answer 1

Given data:

The given table.

The expression for given table can be written as,

`t(p)=a+bp`

Substitute the given ( 1,6) in the above expression.

`\begin{gathered} 6=a+b(1) \\ b=6-a \end{gathered}`

Substitute (5, 20.4) in the expression.

`20.4=a+5b`

Substitute (6-a) in above expression.

`\begin{gathered} 20.4=a+5(6-a)) \\ -9.6=-4a \\ a=2.4 \end{gathered}`

The value of b is,

`\begin{gathered} b=6-2.4 \\ =3.6 \end{gathered}`

The expression is t(p)=3.6p+2.4.

Thus, the third option is correct.
