Recall the compound interest formula
Where r = 0.04, n = 12 since compounded monthly, t = 30, and p, initial value, is 24000.
Plug them in, 79523.95 seems to be the solution.
Answer:
70 minutes or you could say 1 hour and 10 minutes
Step-by-step explanation:
To solve this problem, let us first find for the binary
equivalents of the numbers. They are:
Decimal --> Binary
+ 29 --> 00011101
+ 49 --> 00110001
- 29 --> 11100011
- 49 --> 11001111
Now we apply the normal binary arithmetic to these converted
numbers:
(+ 29) + (- 49) ---> 00011101 + 11001111 =
11101100 ---> - 20 (TRUE)
(- 29) + (+ 49) ---> 11100011 + 00110001 = 00010100
---> + 20 (TRUE)
(- 29) + (- 49) ---> 11100011 + 11001111 = 10110010
---> - 78 (TRUE)
