Answer:
This number can be found using the Rule of 70, which describes the formula dt = 70 / r, where dt is the doubling time, and r is the annual rate of growth.
Step-by-step explanation:
24/6 = 4
20 x 2 = 40 x 2 = 80 x 2 = 160 x 2 = 320
20 ---> 320 in the first day.
Keep doing this equation. Multiply each day's end result by 2 four times for 9 more days.
5.99(1.75)= 10.4825
10.4825 to the nearest hundredth is 10.48
$10.48
Well, the formula for simple interest is

"I" is interest, "p" is the principal, "r" is the rate, and "t" is the time.
If you substitute the numbers, you get

When you multiply them together, you get

So, the simple interest for 3.5 years is $210.
But, in order to get the total balance, you have to add the interest and the principal together.

So, the balance after 3.5 years is $1,210.
Answer:
11/20 or 99/180 days
Step-by-step explanation:
55/100 converted to ?/180
180/100=1.8
so you would do the same on the numerator which is 55*1.8=99
99/180= 33/60=11/20
