x = 4/5 = 0.8
y = (4/x * x) + √x + 0.2 - 5x.
First, let's plug 0.8 in for x
y = (4/0.8 * 0.8) + √0.8 + 0.2 - 5(0.8)
(4/0.8 * 0.8) the 0.8s cancel out leaving just 4
y = 4 + √0.8 + 0.2 - 5(0.8)
5 * 0.8 = 4
y = 4 + √0.8 + 0.2 - 4
Add all the terms together
y = 1.09.
First find the future value of an annuity ordinary using the formula of
Fv=pmt [(1+r)^(n)-1)÷(r)]
Fv future value?
PMT 4000
R 0.05
N 15 years
Fv=4,000×(((1+0.05)^(15)−1)÷(0.05))
Fv=86,314.25
Then deducte the 15% tax bracket from the amount we found to get the effective value of Yon's traditional IRA at retirement
86,314.25−86,314.25×0.15
=73,367.11
Answer:
3.80
Step-by-step explanation:
Answer: 37.5%
Explanation:
Percentage is defined as parts of an amount in 100 parts of a basis. This must be stated mathamatically for better understanding and for calculations. It is the ratio:
% = (parts / base) × 100.
In this case you need to express the amount of butter as a part in 100 parts of all purpose flour, which, using the above definition, is:
% butter = (0.75 pounds of butter / 2 pound of flour) × 100
% butter = 0.75 × 100 / 2 = 75 / 2 = 37.5
The answer is expressed as 37.5%.
