Her first rate was faster. The 10 minutes with a change in elevation of -200ft.
In order to solve this you need to have the same minutes. In this problem, I just simply took the 10 minutes and the -200ft and doubled it. Now both rates have 20 minutes. The first rate would have gone -400ft in 20 minutes while the second rate was only -300ft in 20 minutes. I hope this wasn't confusing, and I'm willing to explain more.

Figure out slope by using:
(y2-y1)/(x2-x1)

Plug in values:
29.98-15.49/50-25

Simplify:
14.49/25 = 0.5796

Then, use this ratio for the 40 lbs bag. So, then:
40*0.5796 = 23.184

So, your price for the 40 lbs bag should be $23.18 because cents only go up to 2 decimal places (otherwise, it would be $23.184).

You'll use the chart to start your equation. There are 2000 grams to a kilogram. One batch is 1425grams. To get 2 kilograms she needs 2000 grams. So 2000-1425= your answer. For question 2, there are 1000 ml in 1 Liter. Use this information to see which will hold more liquid, 2 bottles or 8 cans.
