Chapter SH, Problem 3.8MPS

a.

To determine

To graph the data.

Explanation of Solution

Given:

The given data is

  

Calculation:

The graph of the data is shown below-

  

b.

To determine

To write an equation to describe the relationship.

Answer to Problem 3.8MPS

  $y=1.25x$

Explanation of Solution

Given:

The given data is

  

Calculation:

It is seen that for every increase in number of pounds by $1$ , there is an increase of $\$1.25$ .

So the equation is -

  $y=1.25x$

Where $x$ is the number of pounds and $y$ is the amount.

Therefore, the equation is $y=1.25x$

c.

To determine

To find the cost of $9.5$ pounds of strawberries.

Answer to Problem 3.8MPS

  $\$11.875$

Explanation of Solution

Substituting the value of $x=9.5$ in the equation-

  $\begin{array}{l}y=1.25x\\ y=1.25\times 9.5\\ y=11.875\end{array}$

Therefore, amount earned will be $\$11.875$ .
