B. Obviously all the numbers have to do with one and it’s 30. If it’s wrong let me know !
The first answer is B: 2 1/2
4 5/6 is put there twice except the last one is subtracting so you can put, 4 5/6 - 4 5/6 = 0 therefore the only number left is 2 1/2
the second one I really don't know sorry:(
The third answer is C because the cases come in 24. But they didn't tell you how many case she brought so the variable has to be by 24 and they took 43 which is the subtracting factor. So the answer is C.
And I also don't know the last one again sorry:(
Answer:
Don't know the exact equation but trying to explain
X is what the stuff that problem saying. Let's say you have books from library and you're returning them late you will pay $30 dollars for each of them
Answer:
The value of this investment at the end of the 5 years is of $662.5.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Dina invests $600 for 5 years at a rate of 2% per year compound interest.
This means that
. Thus



Calculate the value of this investment at the end of the 5 years.
This is A(5). So

The value of this investment at the end of the 5 years is of $662.5.
