Answer:

ratios, rates, and unit rates can be used to solve how much of something there is compared to another thing.  Ex: There are 3 times the amount of apples compared to oranges.  How many apples are there if you have 2 oranges?  For a ratio, you would make it 3:1.  Then substitute the 1 for 2.  For a rate, you would make it 3 apples per oranges.  Then do the same thing you would do for the ratio.  Unit rates work the same way.

Step-by-step explanation:

sorry if this isn't the answer you were hoping for, but I tried

Y=kx
12=-4k
  k = -3

so when y = 15
y = kx
15 = -3x
  x = -5

----------------

$50 / 0.04 = $1250 (4% interest)

so
1250 * 0.06 = $75

answer
interest $75 at 6%

-----------------------------

y = kx
1/4 = 4k
k = 1/16

when x = 5
y = kx
y = 1/16(5)
y = 5/16 

-----------
y = kx
-5 = 4k
k = -5/4

direct equation
y = -5/4x
