It costs $3.56 to buy a pack of pencils. Which of the following equations shows the amount of money needed, x, to buy k packs of pencils?x = 3.56k
k = 3.56x
x = 3.56 + k
k = 3.56 + x

Answers

The total price would be $3.56 times however many you bought, so the correct equation would be x = 3.56k.

Answer:

It would be A.

Step-by-step explanation:

x = 3.56k

Compute the amount of interest earned in the following simple interest problem. A deposit of $5,000 at 8.5% for 120 days = _____. $140.25
$1,402.50
$14,025
$51,000

Answers

Answer:

Option (a) is correct.

The  amount of interest earned in the given simple interest problem is $140.25

Step-by-step explanation:

Given : A deposit of $5,000 at 8.5% for 120 days.

We have to calculate the  amount of interest earned in the given simple interest problem.

Using Simple interest formula,

SI=(P * r* t)/(100)

Where SI denotes simple interest

P denotes principal

R denotes rate of interest

t denotes time period.

Thus,

Given : P = $5,000

r=  8.5%

t =  120 days  

1 year = 365 days.

So , 120 days = (120)/(365) year.

Substitute, we get,

SI=(P * r* t)/(100)

SI=(5000 * 8.5* 120)/(100* 365)

On simplify, we get,

SI =$ 139.72

Thus, out of given options nearest value is $140.25 (approx)

Thus, the  amount of interest earned in the given simple interest problem is $140.25

I = p * r * t
I = 5000 * .085 * (1/3)
I = 140.25
