Answer:
Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 0.9
Step-by-step explanation:
x variable represents total megabytes of data used
y variable represents total monthly charges
The company charges $155 (y) for 100 megabytes (x) means that the point (100, 155) belongs to the equation.
The company charges $245 (y) for 200 megabytes (x) means that the point (200, 245) belongs to the equation.
With these two points, the slope is computed as follows:
(245 - 155)/(200 - 100) = 0.9

Answer:
6.08 kg bag unit price: $1.72
7.48 kg bag unit price: $1.86
6.08 kg bag is the better buy
Step-by-step explanation:
To find unit price, divide the price by the amount. 10.47 divided 6.08 equals 1.7203947. Round it to the nearest cent to get 1.72. So, the unit price for the first bag is $1.72. Next divide 13.88/7.48 to get 1.85561. Round it to the nearest cent to get 1.86. So, the unit price for the second bag is $1.86 per kg. The better buy is the cheaper one, so the 6.08 kg bag is a better deal. Hope this helped!
