Answer:
x = 32800
Step-by-step explanation:
56 × 328 + 162 × 44 + 166 × 44 - x = 0
18368 + 7128 + 7304 − x = 0
32800 - x = 0
-x = -32800
x = 32800
Using simple interest, it is found that $13,872 was loaned at 9%.
<h3>Simple Interest</h3>
The amount of money after t years in simple interest is modeled by:

In which:
- r is the interest rate, as a decimal.
The interest earned is:

A bank loaned out $14000, in two parts, hence:

Part of it at the rate of 9% per year and the rest at 17% per year, hence:

The interest received in one year totaled $2000, hence:

Then:



Isolating
as a function of
, then we can replace on the equation for the first interest.



Then:






$13,872 was loaned at 9%.

Answer:
2 cars
Step-by-step explanation:
105 + 895 + 1120 = 2120
He has to pay 2120 of downpayment
2120 - 1919 = 201
Subtract what he already has
He needs 201 more dollars to rent his first apartment
He needs to do 1.21818182 cars...
You cant do 1/5 of a car so he has to do 2 cars
If you would like to know what is the full cost if 75% is £60, you can calculate this using the following steps:
75% of x = £60
75% * x = £60
75/100 * x = 60 /*100/75
x = 60 * 100 / 75
x = £80
Result: The full cost is £80.
Answer:
160 for each
Step-by-step explanation:
A normal distribution means that mean = median = mode. Furthermore, in a normal distribution, 68% of values are within 1 standard deviation of the mean, 95% of values are within 2 standard deviations, and 99.7% are within 3 standard deviation.
The mean is 150 and the standard deviation is 15. 165 and 135 1 standard deviation away from the mean, so 68% of values are between 135 and 165. This means that 32% of values are not between those values. A normal distributuion is symmetric, so 16% of values are greater than 1 standard distribution and 16% are less. Therefore, 16% of values (160) are less than 135 and 16% of values (160) are greater than 165
