Answer:

Step-by-step explanation:

I typed this into the calculator however, the steps are listed below.

-6×10(-1)=-0.6

[10(-1)=0.1]

-3×10(-2)=-0.03

[10(-2)=0.01]

-0.6÷-0.03=20

(If you do not know how to divide fractions please google. there are multiple ways.)

A store bought a tent for $230 andmarked it up 65%. The store sells thetent with an 8% tax, what is the totalcost of the tent?

Len [333]

The cost for buying the tent is $230.

65% was increasesd for selling. Then the rate is

$\begin{gathered} 230\times\frac{65}{100}=14.95 \\ So,\text{ the marked price=230+14.95=}244.95 \end{gathered}$

The tax is 8%. So this is from the marked price.

$\begin{gathered} \frac{8}{100}\times244.95=19.56 \\ 244.95-19.56=225.39 \end{gathered}$

Therefore the total cost of the tent is $225.39.

What is the total investment of $2150 invested at 5.3% for 16 years and compounded continuously?

sladkih [1.3K]

Answer:

The total investment is $5020.19

Step-by-step explanation:

Given : $2150 invested at 5.3% for 16 years and compounded continuously

To find : What is the total investment?

Solution :

The formula of continuously compounded interest is

$A = Pe^{rt}$

Where A = amount invested

P = principal = $2150

e = Euler's number (on calculator)

r = interest rate as decimal = 5.3%=0.053

t = time in years = 16 years

Substitute the value in the formula,

$A = Pe^{rt}$

$A = 2150\times e^{0.053\times 16}$

$A = 2150\times e^{0.848}$

$A = 2150\times 2.3349$

$A = 5020.19$

Therefore, Option 4 is correct.

The total investment is $5020.19.
