I think is C or D, but I'm not to sure
Answer:
well the money doubles every 6 years but its only been 4 so
7,400 x 4 = 29,600
$29,600 is the answer
Here is the set up:
Side 1 is 4x.
Side 2 is 5x + 3
Side 3 is 5x + 1
The perimeter is 102.
Perimeter = side 1 + side 2 + side 3
102 = 4x + 5x + 3 + 5x + 1
102 = 14x + 4
Take it from here.
I asssume we want to find the original price
so marked up 50% means if original price=100, then marked up price=50+100=150%
so
36.76=150%
hack, since 150=3 times 50 and 2 times 50=100, divide 36.76 by 3 then mutiply by 2
36.76=150%
divide both sides by 3
12.25333333333=50%
multiply both sides by 2
24.5=100%
original price=$24.50
The answer is B 1:2. I hope you get it right
