Answer:
- $9,000 at 15%
- $4,000 at 10%
Step-by-step explanation:
Let x represent the amount borrowed at 15%. Then the amount borrowed at 10% is (13000-x). The interest at the end of the year is ...
   0.15(x) + 0.10(13000 -x) = 1750
   0.05x = 1750 -1300 . . . . . . . . . . . . simplify, subtract 1300
   x = 450(20) = 9000 . . . . . . . . . . multiply by 20
$9,000 was borrowed at 15%; $4,000 was borrowed at 10%.

=151 is the anser for 10 people  you need to figure out how much it costs per person to find your complete answer and don't forget get that your adding "Leo " into the eqation
 
        
             
        
        
        
The answer is a = 3/4 = 0.75
First get rid of the paranthesis, 

Then set the denominators equal:

Then remove the denominators and solve:

Eliminate -12a^2 by adding 12a^2 to both sides:

Take the fourth root of them or take the square root twice:
![\sqrt[4]{256 {a}^{4} }  =  \sqrt[4]{81}   \\  4a = 3](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B256%20%7Ba%7D%5E%7B4%7D%20%7D%20%20%3D%20%20%5Csqrt%5B4%5D%7B81%7D%20%20%20%5C%5C%20%204a%20%3D%203)
Divide both sides by 4:
 
 
        
        
        
7. increasing; non-linear
8.A. y=4^x
9.A. y=6x
