9. Karen Cares is a Community aid agency to help underprivileged house cats and their owners who are having difficulty getting along find counseling.
Last year 1587 kindhearted people donated to Karen's. The average
donation was $15 per person. They have set a goal to have a 10% increase
in donations this year. How much total money does the organization hope
to take in this year? If an hour-long counseling session cost $50, how many
more sessions will the donated money cover this year than were covered last
year?

Step-by-step explanation:

In most cases the first step is to create an equation to solve for the missing variable

But in this case we are already given the equation

(7.25h + 5 = 6.5h + 10.25)

All we have to do is solve for h

7.25h + 5 = 6.5h + 10.25

Step 1 subtract 5 from both sides

7.25h = 6.5h + 5.25

Step 2 subtract 6.5h from both sides

0.75h = 5.25

Step 3 divide both sides by .75

h = 7

So at 7 hours the cost will be the same for both instructors
