Answer:
The markup amount on the cost 39.99 $ will be: 8.78 $
Step-by-step explanation:
Given
- The cost = 39.99 (Let say in $)
As
22% = 0.22
The markup of 22% on the cost can be calculated by multiplying the cost by 22% or 0.22

Therefore, the markup amount on the cost 39.99 $ will be: 8.78 $
Answer:
11 years approx
Step-by-step explanation:
Given data
P=$1000
A=2000
R=6.5%
T= ?
Calculate time, solve for t
t = ln(A/P) / r
substitute
t=ln(2000/1000)/0.065
t=ln(2)/0.065
t=0.693/0.065
t=10.66
Hence the time is 11 years approx
