Answer:

$27.71

Step-by-step explanation:

Price of 1 DVD: $9.19

Price of 4 DVDs: 4 * $9.19 = $36.76

Discount: 25%

Now we find 25% of $36.76.

25% of $36.76 =

= 0.25 * $36.76

= $9.19

The 25% discount amounts to $9.19. We now subtract $9.19 from $36.76 to find the discounted price.

$36.76 - $9.19 = $27.57

Now we need to apply the 7.75% tax to $27.57.

7.75% of $27.57 =

= 0.0775 * $27.57

= $2.14

The sales tax is $2.14.

Now we add the sales tax amount to the total discounted price.

$27.57 + $2.14 = $29.71

Answer: $27.71

The function in Exercise represents the rate of flow of money in dollars per year. Assume a 10-year period at 8% compounded cont

anzhelika [568]

Answer:

a) The present value is 688.64 $

b) The accumulated amount is 1532.60 $

Step-by-step explanation:

a) The preset value equation is given by this formula:

$P=\int^{T}_{0}f(t)e^{-rt}dt$

where:

T is the period in years (T = 10 years)
r is the annual interest rate (r=0.08)

So we have:

$P=\int^{T}_{0}(0.01t+100)e^{-rt}dt$

Now we just need to solve this integral.

$P=\int^{T}_{0}0.01te^{-rt}dt+\int^{T}_{0}100e^{-rt}dt$

$P=e^{-0.08t}(-1.56-0.13t)|^{10}_{0}+1250e^{-0.08t}|^{10}_{0}$

$P=0.30+688.34=688.64 $$

The present value is 688.64 $

b) The accumulated amount of money flow formula is:

$A=e^{r\tau}\int^{T}_{0}f(t)e^{-rt}dt$

We have the same equation but whit a term that depends of τ, in our case it is 10.

So we have:

$A=e^{r\tau}\int^{T}_{0}(0.01t+100)e^{-rt}dt=e^{0.08\cdot 10}P$

$A=e^{0.08\cdot 10}688.64=1532.60 $$

The accumulated amount is 1532.60 $

Have a nice day!
