Thomas rents a car for his vaccation the milliage included with the 54 miles forer every mile he drives over 54 miles he needs t

Sauron [17]

Answer:

$27

Step-by-step explanation:

Thomas rents a car for his vacation. The mileage include with the rental is 54 miles. For every mile he drives over 54 miles, he needs to pay $1 4/5. If he drives 69 miles, how much extra does he need to pay?

Total mileage included with the rental = 54 miles

Additional cost per mile after 54 miles = $1 4/5

Total miles Thomas drives = 69 miles

Extra miles Thomas drives = 69 miles - 54 miles

= 15 miles

how much extra does he need to pay?

Extra cost Thomas needs to pay = Additional cost per mile after 54 miles * Extra miles Thomas drives

= $1 4/5 * 15 miles

= 9/5 * 15

= (9 * 15) / 5

= 135/5

= 27

Extra cost Thomas needs to pay = $27

You deposit the same $10,000 into a bank account at 4% annual interest. How long will it take for the $10,000 to compound to $30

Readme [11.4K]

Answer:

time = 28 years

Step-by-step explanation:

Given,

principal amount = $10,000

rate = 4%

total amount = $30,000

According to compound interest formula

$A\ =\ P(1+r)^t$

where, A = total amount

P = principal amount

r = rate

t = time in years

so, from the question we can write,

$30000\ =\ 10000(1+0.04)^t$

$=>\ \dfrac{30000}{10000}\ =\ (1+0.04)^t$

$=>\ 3\ =\ (1.04)^t$

by taking log on both sides, we will get

=> log3 = t.log(1.04)

$=>\ t\ =\ \dfrac{log3}{log1.04}$

=> t = 28.01

So, the time taken to get the amount from 10000 to 30000 is 28 years.
