It is 8 percent of 50.
This is 1 way-
<span>4/50=%/100 You now have a proportion. Cross multiply.
50%=400 Replace % with any variable.
50x=400 Now divide both sides of the equation by 50.
x=8
</span><span>
(% is basically the percentage of 4 of 50 over 100. its much easier to solve </span>percentage problems when the percentages are over 100. 100 represents a full percentage.
example- 4 of 100 is 4% of 100)
2nd example-
Since the percentage can be found if over 100 as well (%/100), and since 100 is a multiple of 50, we can do 4 of 50 (which would look like 4/50) and multiply both numbers by 2 to get the percentage. These are our steps:
<u />4/50× 2/2=
8/100
Therefore, 4 of 50 is 8% of 50
First, you would create an equation for this problem.
(680 - 240) ÷ 8 mi
Now, all you would have to do is solve it. Using the order of operations (PEMDAS), you would start in the parenthesis.
(680 - 240) ÷ 8 mi
440 ÷ 8 mi = 55 ft
Your evaluation would increase 55 feet per mile.
I hope this helps!

Answer: $2,150
Step-by-step explanation:
The amount taken was $2,000
The interest rate was 2.5%
Period is 3 years.
The formula for simple interest is:
= Amount * ( 1 + rate * time)
= 2,000 * ( 1 + 2.5% * 3)
