By earning an annual interest, the amount of money that can be earned after n years is calculated through the equation,
F = P x (1 + r)^n
Substituting the known values,
2,000 = 500 x (1 + 0.06)^n
The value of n from the equation above is 23.79 or approximately 24 years.
Answer, z10
Step-by-step explanation:
A = $ 9,845.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8.25%/100 = 0.0825 per year,
then, solving our equation
A = 4400(1 + (0.0825 × 15)) = 9845
A = $ 9,845.00
The total amount accrued, principal plus interest,
from simple interest on a principal of $ 4,400.00
at a rate of 8.25% per year
for 15 years is $ 9,845.00.
Step-by-step explanation:
d=days not used
50-2d = 40-1.5d
subract 40 each side
10-2d =1.5d
10= 0.5d
20=d
After 20 days the value of the gift cards will be equal.
20*2=40 50-40=10 ($10)
20*1.5=30 40-30=10 ($10)
each card will have a value of $10 after 20 days,when both cards have equal value
