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

`w=83\ pounds`

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`
