Answer:
Step-by-step explanation:
An investment banker received a bonus and invested that money in two investments. He put a certain sum
of money in the first investment that returned 7% interest after one year. In the second investment he
Invested four times that of the first investment and got a 12% interest return after one year. If the total
interest from his investments after one year was $8,525.00, find the amount invested at each interest rate.

Find K and M
Make K the subject in: 

Substitute
in 
![\frac{1}{5} * [3 * ( M - 24) - 24] = \frac{1}{3} * M](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20%2A%20%5B3%20%2A%20%28%20M%20-%2024%29%20-%2024%5D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%2A%20M)
Open brackets
![\frac{1}{5} * [3M - 72 - 24] = \frac{1}{3} * M](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20%2A%20%5B3M%20-%2072%20-%2024%5D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%2A%20M)
![\frac{1}{5} * [3M -96] = \frac{1}{3} * M](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20%2A%20%5B3M%20-96%5D%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%2A%20M)
Multiply both sides by 15
![3* [3M -96] = 5 * M](https://tex.z-dn.net/?f=3%2A%20%5B3M%20-96%5D%20%3D%205%20%2A%20M)

Collect like terms


Divide both sides by 4

Answer:
1) x<2.5 2) x<2.5 (both are smaller numbers than 2.5)
Step-by-step explanation:
I'm sure there is a easier way to figure this question out but how I did is by simply imputing numbers smaller or bigger into where the x is. For example, I imputed 3 into -4x+5>-5. So, -4(3)+5>5, = -7>5, this is false, so x must be smaller than 2.5 in order for this to be true.
