Question

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?

Answer 1

Answer:

$w=83\ pounds$

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

$c=0.35w+7$ -----> linear equation that describes the line of best fit

so

Substitute in the equation the value of $c=\ 36.05$ and solve for w

$36.05=0.35w+7$

$0.35w=36.05-7$

$0.35w=29.05$

$w=29.05/0.35=83\ pounds$
