The answer is B (second choice)
You basically need to find the slope of (2,-3) and (3,-1). Where x is 2, y is -3 and were x is 3, y is -1.
Slope is y2-y1/x2-x1
2 is your slope. So, the average rate of change from x=2 and x=3 is 2.

Answer:
Step-by-step explanation:
500+7500=8000
150x50=7500
8000 books were sold over the course of 50 days
The sale price is $3. 17%, or .75*$12 is $9. $9 is the amount of money that you save on the DVDs. So, you would do $12-$9 which would equal $3. You would end up paying $3 for the DVD. In this problem, $12 represents the original price of the DVD and $9 is the amount of money you save on the DVD. $3 is the amount of money you spend on the DVD. $3 is also the sale price of the DVD. In any type of these problems you do %* original price. This will give you the amount of money you save. You subtract the amount of money you save from the original price, and you will get the sale price which is what you will be paying for whatever is being represented in the problem.

Solve for the R by simplifying both sides of the equations, then isolating the variable.
Exact form: R=787/29
Decimal Form: R=27.13793103.....
Mixed Number Form: R= 27 4/29
