3. After one year, an investor received interest of $1,180 on investments totaling $12,000. One of his two investments earned 9% in simple interest and the other earned 11% in simple interest. How much of the $12,000 earned 9% and how much earned 11%? ​

i’m here for points.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

f . i can go whenever i feel like it bc it is confidential meaning only i would know how much i deposited besides the bank and they wouldnt care bc when you make a deposit you are using their services which means they are using there competition and gaining more customers

and if they dont well then thats less customers for them in a less profitable way
