Answer:

$46875.

Step-by-step explanation:

We have been given that Dr. Drake buys a sailboat for 125000. He borrows the money at an APR of 7.5% for five years.

We will find total interest after 5 years by using simple interest formula.

$A=P(1+rT)$ , where,

A= Amount after T years.

P= Principal amount.

r= The annual interest rate (in decimal form).

T= Time in years.

First of all we will convert our given interest rate from percent to decimal form.

$7.5\text{ Percent}=\frac{7.5}{100} =0.075$

Now let us substitute our given values in above formula.

$A=125,000(1+(0.075*5))$

$A=125,000(1+0.375)$

$A=125,000(1.375)$

$A=171875$

To find the amount of total interest we will subtract principal amount from 171875.

$\text{Total amount of interest}=171875-125000$

$\text{Total amount of interest}=46875$

Therefore, the total interest after 5 years will be $46875.

Answer:

Step-by-step explanation:

Let the digits of the number be represented by t for the tens digit and u for the units digit.

u = 2t . . . . . . . . the units digit is twice the tens digit

2(10t +u) = (10u +t) +9 . . . . . double the number is 9 more than its reverse

Substituting for u, we have ...

2(10t +2t) = 10(2t) +t +9

24t = 21t +9 . . . . . . . . . . . collect terms

3t = 9 . . . . . . . . . . . . . subtract 21t

t = 3 . . . . . . . . . . . divide by 3

u = 2t = 6 . . . . find u

The number is 36.
