Find the simple interest on a $2,450 principal deposited for six years at a rate of 3.77% $701.19, $601.02, $531.57, $554.19 what the answer​

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

answer is  

d.

all of the above

hope you get this right
