Compound interest of 5% means multiplying by 1.05 each year.
Let’s call the missing value x
To find x, we need to do:
(X) * 1.05 * 1.05 * 1.05 = 8000
So, to find x, divide 8000 by 1.05^3
721*8= 5768.................
I believe the answer is 21
For 4 you just need to multiply the 7 and 33 together and add 32. Then put your awnser over 33. (if it is asking for the fraction)
