A scatter plot relates the weight (w) in pounds of an order to the charge (c) in dollars to ship the order. The equation c = 0.35w + 7 describes the line of best fit. What would be the expected weight of an order when the cost to ship the order is $36.05?

Respuesta :

Answer:

[tex]w=83\ pounds[/tex]

Step-by-step explanation:

Let

w------>  the weight in pounds of an order

c------>  the charge in dollars to ship the order

we know that

[tex]c=0.35w+7[/tex] -----> linear equation that describes the line of best fit

so

Substitute in the equation the value of [tex]c=\$36.05[/tex] and solve for w

[tex]36.05=0.35w+7[/tex]

[tex]0.35w=36.05-7[/tex]

[tex]0.35w=29.05[/tex]

[tex]w=29.05/0.35=83\ pounds[/tex]
