" break even " is when ur expenses = revenue.....there is no profit made when u break even
expenses : 0.35x + 770
revenue (ur income) : 0.55x
so they have to equal to break even...so set them equal to each other and solve for x
0.35x + 770 = 0.55x
770 = 0.55x - 0.35x
770 = 0.2x
770 / 0.2 = x
3850 = x <== they must sell 3850 copies to break even

Given:
The table of values.
To find:
The average rate of change for the given function from x = −1 to x = 2.
Solution:
From the given table it is clear that y=-3 at x=-1 and y=3 at x=2.
Formula for average rate of change is

Using the above formula, the average rate of change for the given function from x = −1 to x = 2 is




Therefore, the correct option is D.
First we have to figure out how many hours have passed. Since 1PM also means 1300 hours, we'll subtract 9 from 13. 13-9=4. therefore, 4 hours have passed. if it gains 4 minutes every hour, we'll multiply the amount of hours that have passed by the amount the clock gains every hour. 4x4=16. now we subtract 16 from 1300 because the clock is ahead of the real time, but remember and hour only has 60 minutes! 1300-16=1244. Therefore, the correct time is 12:44PM.
