Answer:

P = $6923

Step-by-step explanation:

The simple interest formula is given by

1) I = principal  *interest rate * time period

where I is the interest

The amount due after the time period is given by:

2) T = principal + I

After three months, you have $9.000, so T = 9000. The present value P is the principal. We have that:

9000 = P + I

I = 9000 - P

In our problem, we have that the time period is 3 months and out interest rate is 10%.

Replacing in 1)

9000 - P = P*0,1*3

9000 = 0.3P + P

1.3P = 9000

P = $6923

So the present value P is $6923

Blababa [14]

Answer:

8.5 inches

Step-by-step explanation:

First let's find the time t when the depth of the snow is 7 inches.

To do this, we just need to use the value of D = 7 then find the value of t:

7 = 1.5t + 4

1.5t = 3

t = 2\ hours

We want to find the depth of snow one hour from now, so we just need to use the value of t = 3 to calculate D:

D = 1.5*3 + 4

D = 4.5 + 4 = 8.5\ inches

The depth of snow one hour from now will be 8.5 inches.
