If an amount of money is invested at an annual interest rate of 6%, it doubles every 12 years. If Alejandra invests $500, how lo
sergiy2304 [10]
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.

A principal of $4400 is invested at 8.25% interest, compounded annually. how much will the investment be worth after 15 year's?
vladimir2022 [97]
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.

Tavon has a $50 gift card that loses $2 for each 30-day period it is not used. He has a $40 card that loses $1.50 for each 30-da
prohojiy [21]
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
