Answer:
2
Step-by-step explanation:
Notice the question of which number is being subtracted 12 times in order for the answer to be zero is the same as finding b.
Notice 24 is being divided by b to get 12 as result.
The question is then: by what number we divide 24 to get 12?
It is 2 since:

And notice if we subtract 12 times b from 24 we actually get 0:

Answer:
=$2739.81
Step-by-step explanation:
To find the total amount if the interest is compounded, we use the compound interest formula.
A=P(1+R/100)ⁿ
A is the amount, P- principal, is the invested amount R is the % interest rate, n is the number if periods.
If compounded semi-annually, it means we have two periods in 1 year
The rate is also divided by 2
Thus 25 years have (25×2) = 50 periods.
A= 750(1+5.25/200)⁵⁰
=750(1.02625)⁵⁰
=$2739.81
