Answer:
marginal revenue is -6
and production levels 200, 50
Explanation:
given data
R(x) = 10 x - 0.04 x²
solution
we have given
R(x) = 10 x - 0.04 x²
so here R'(x) is
R'(x) = 10(1) - 0.4 (2x)
R'(x) = 10 - 0.8 x ....................1
so here at x is 20 marginal revenue will be
R'(20) = 10 - 0.8(20)
R'(20) = 10 - 16
R'(20) = - 6
and
when revenue is $400
R(x) = 400
400 = 10 x - 0.04 x²
x= 200, 50
Stephanie's marginal tax rate is 15%.
<u>Explanation:</u>
The Average tax rate is 8%
she pays $3.75 as the tax on $25 which makes tax rate at this point =3.75/25
= 15%
The Marginal tax rate is the percentage of income that has to be paid as tax as a result of a change in the income bracket.
For instance, if tax rate until $1-$1000 is 10%
and for $1000 and above is 20%.
So for every $ earned over and above $1000.The marginal tax rate for that sum is 20%.
Answer:
Total puzzles solved expected by an employee: 2.61
Explanation:
we multiply each outcome by the probability adn then add them together. Thus, we are doing a weighted-average
0 x 0.06 = 0.00
1 x 0.16 = 0. 16
2 x 0.19 = 0.38
3 x 0.32 = 0.96
4 x 0.24 = 0.96
5 x 0.03 =<u> 0. 15 </u>
Total puzzles 2.61
Answer:
21.26%
Explanation:
Calculation for the Rate of return that the
investor receive on the XYZ Fund last year
Using this formula
Rate of return =Current value - original value +Income distributions+ Capital gain distributions) / original value) x 100
Where,
Current value =$19.47
Original value =$17.50
Income distributions=$0.75
Capital gain distributions=$1.00
Let plug in the formula
Rate of return($19.47 - $17.50 + $0.75 + $1.00)/$17.50
Rate of return =($1.97+0.75+$1.00)/$17.50
Rate of return=$3.72/$17.50
Rate of return =0.2126*100
Rate of return =21.26%
Therefore the rate of return that did investor receive on the XYZ Fund last year will be 21.26%
