Question

Jesse takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. A rat weighs 3.5 pounds and costs $4.50 per week to feed, while a Beagle weighs 30 pounds and costs $9.20 per week to feed.

Answer 1

Answer:

The slope is  $s =$ $0.1774 / pounds

Step-by-step explanation:

From the question we are told that

   The weight of the rat is $w_1 = 3.5 \ pound$

     The cost of feeding the rat per week is $c_1 =$$4.50

     The weight of a Beagle is  $w_2 = 30 \ pound$

     The cost of feed a Beagle per week is  $c_2 =$$9.20

Now the slope can be evaluated mathematically as

           $s = \frac{c_2 -c_1 }{w_2 -w_1 }$

substituting values

            $s = \frac{9.20 -4.50 }{30 -3.5 }$

           $s =$ $0.1774 / pounds
