I would do this with a proportion. we know 4 quarter hours are in 1 hour, so how many are in 5?
4/1 = x/5
cross multiply
1*x=4*5
x=20
there are 20 quarter hours in 5 hours.

There is a few ways to get the result.
Lets try this.
First calculate how many minutes are in the 5 hours.
60min*5=300min - in 5 hours
Now, knowing that quarter is 15min we can divide 300 by 15 to get the result, so
300:15=20 - its the result.

How much interest does Ms. Paris earn on an $1800 loan for 6 months with a simple interest rate of 8.5%?
ddd [48]

Answer:

$1136.60

Step-by-step explanation:

The formula for exponential growth is f(x) = a(1 + r)^x where a is the initial value, r is the growth rate, and x is the number of time intervals.

We know that Mr. Paris starts with an $1800 initial value, so we can substitute that into the equation:

f(x)=1800(1 + r)^x

We also know the time intervals is 6 months. So that can be substituted as well:

f(x)=1800(1 + r)^6

They told you that the growth rate is 8.5%, which is 0.085 of 1.

f(x)=1800(1 + 0.085)^6

Add the 2 values in the parentheses and you get 1.085

f(x)=1800(1.085)^6

Now solve.

Order of operations requires you to raise 1.085 to the 6th power before multiplying by 1800. So then you have this:

1800(1.63146751) = 2936.64152. That rounds to 2936.60

So $2936.60 is the total amount of money in the bank account, but were looking for the interest earned, which is the difference between the end value and the initial value.

$2936.60 - $1800 = $1136.60

Genrish500 [490]

Answer:

The amount of increase per \frac{1}{3}  hour by $1.

Step-by-step explanation:

Julian charges $10 for every \frac{1}{3} hour he walks a dog.

He increases his fee by 10%

Now we have to find 10% of $10

Amount increased = \frac{10}{100} .10 = 1

So the amount increased by $1.

The amount of increase per \frac{1}{3}  hour by $1.
