A law firm is going to designate associates and partners to a hug new case. The daily rate of charged to the client for each ass

goldenfox [79]

Answer:

There are 3 associates and 5 partners assigned to the case.

Step-by-step explanation:

We know that the combined cost of the unknown number of associates and partners equals $6500 per day, and that the amount of associates and partners assigned to the case equals 8, so we can derive these two equations (where a is associates and p is partners):

500a + 1000p = 6500

a + p = 8

Let's use the second one first to isolate the a..

a + p = 8

If we subtract p from both sides of the equation we get:

a = 8 - p

Now we may use this in our original equation to solve for p

500(8-p) + 1000p = 6500

If we simplify by distribution, we get:

4000 - 500p + 1000p = 6500

Now let's add those two p's together...

4000 + 500p = 6500

And subtract 4000 from both sides to get:

500p = 2500

Now finally, divide both sides of the equation by 500 to get p:

p = 5

We now have the number of partners involved (5), and we know that the amount of associates plus the amount of partners assigned to the case equals 8, so we can plug the amount of partners assigned into the second formula to get a:

a + 5 = 8

And by subtracting 5 from both sides we get...

a = 3

Katie works part-time at a Fallbrook riding stable she makes $5 an hour for exercising horses and $10 an hour for cleaning stall

Nookie1986 [14]

In order to at least earn $90, Katie can work exercising horses for 6 hours and cleaning stalls for 6 hours.

Step-by-step explanation:

Let hours of exercising horses be x --> $5 per hour = 5x

Let hours of cleaning stalls be y --> $10 per hour = 10y

Total earning = $\geq 90$

Total hours = 12

Equation 1:

5x + 10y = $\geq 90$

Equation 2:

x + y $\leq 12$

1. Multiply equation 2 by -5

x + y $\leq 12$ (*-5)

5x + 10y = $\geq 90$

-5x - 5y $\leq -60$

5x + 10y = $\geq 90$

2. Solve

-5x + 5x -5y + 10y = -60 + 90

5y = 30

y = 6

x + y = 12

x + 6 = 12

x = 6

Therefore, in order to at least earn $90, Katie can work exercising horses for 6 hours and cleaning stalls for 6 hours.
