Answer:
Bank B because the more often you compound interest, the more interest you earn.
Step-by-step explanation:
Bank A compounds the interest once a year.
Bank B compounds the interest twice a year.
Let's create an example of two investments of the same amount of money, the same interest rate, and the same time. The only difference will be the number of times the interest is compounded per year.
Compound interest formula:
where
A = future value
P = principal invested
r = interest rate
t = number of years
n = number of times interested is compounded in 1 year
Example:
P = $1000
r = 5%
t = 5 years
Bank A: n = 1
Bank B: n = 2
Bank A:
Bank B:
Bank A's investment is worth $1276.28 after 5 years, but Bank B's investment is worth $1280.08 after the same 5 years. Compounding twice per year instead of only once per year earns more interest.
Answer:
Option C.
Step-by-step explanation:
It is given that,
Service cost = $10 per month
Free rental DVD = first 3
Rental after first 3 DVD = $2 per month
We need to find the expressions models for the total amount that Tharun pays, in dollars, in a month when he rents d, DVDs where d>3.
Fixed cost = $10
Rental apply after first three DVD. So,
Variable cost = $2(d-3)
Total cost = Fixed cost + Variable cost
Therefore, the required expression is C.
The quadratic formula is
If the square root in the numerator is equal to 0, we are left with
when you do the plus or minus, the answers will be the same since you are adding and subtracting 0. Therefore there will be two identical rational solutions.
Answer:
(-6)(-5)(3)(-2)(4) = -720
Step-by-step explanation:
-6 time -5 is positive 30 beacuse 2 negatives make a positive
30 times 3 is 90
90 time -2 is -180 because a negative times a positive is a negative
-180 times 4 is -720 :)
