The ratio is 2:13
It starts out as 8:52, but you can take a 4 out of both simplifying it to 2:13
Width = W
Length = 12W - 1
Perimeter = 2L + 2W = 37
In the perimeter equation substitute the length equation in for L to get the equation in terms of W
2L + 2W = 37
2(12W - 1) + 2w = 37
Distribute
2(12W - 1) + 2w = 37
24W - 2 + 2w = 37
26W = 39
W = 3/2 = 1.5
Width = 1.5
Lastly, solve for length
L = 12W - 1
L = (12 • 1.5) - 1
L = 18 - 1
L = 17
Length = 17
Suppose we deposit P dollars. What we can work out is P by considering the interest that is being compounded annually.
After the first year, we would have compounded our deposited amount once:
Using the amount we have in our bank, we compounded it a second and third time:
Let our third year cash be 35 000 to pay off the car.
Thus, P = $31, 476.67, which is the deposit that you need to make on the day.
