Angela has $2,200 to invest at a simple interest rate of 4.5%. If she wants to earn $297 in interest, how long does she have to invest her money?

I will not give you an answer, but I will give you how too get the equation started.

Step-by-step explanation:

set up an equation using:

x= amount invested at 3%

7800 - x = amount invested at 12%

.03(x) + .12(7800 - x) = 504

.03x +936 - .12x = 504

-.09x = -432

x = 4800

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

i dont understand the question? ?
