Answer:
A) P = 240
B) P + Po = 1040
C) P = 270.58
D) P+Po = 1070.58
E) Option B (compound interest) is better, as it generates more interest for the same inicial value, rate of interest and time
Step-by-step explanation:
The formula for simple interest is:
P = Po*r*t
Where P is the interest earned, Po is the inicial value, r is the rate of interest and t is the time.
The formula for compound interest is:
P+Po = Po*(1+r)^t
So we have that:
A) P = 800*0.06*5 = 240
B) P + Po = 800 + 240 = 1040
C) P+Po = 800*(1+0.06)^5 = 1070.58 -> P = 1070.58 - 800 = 270.58
D) P+Po = 1070.58
E) Option B (compound interest) is better, as it generates more interest for the same inicial value, rate of interest and time
Answer:
B
Step-by-step explanation:
2^2 x 5^2 = 100
-Distribute the number outside the parenthesis into all the numbers within.
-Move the numbers with an "x" attached to it to one side and the numbers without an "x" to the other. be sure to change signs as you do (positive to negative, negative to positive)
-subtract or add the numbers on each side together
-divide the number attached to the "x" on both sides (ex. 7x=14, you divide 7)
- you get your answer (x=......)
