The formula for the Pythagorean theorem is,
$20,000 is between $15,000 and $49,999, so we'll use the interest rate of 6.5% (see row 3)
r = 6.5% = 6.5/100 = 0.065
We'll use the decimal form of the interest rate as it is most common for financial math problems.
P = 20,000 is the amount deposited
t = 1 year is the amount of time
We will plug those values into the formula
i = P*r*t
to get the following:
i = P*r*t
i = 20000*0.065*1
i = 1300
So Mark earns $1,300 in simple interest each year.
The answer is x=4 hope it helps
Answer:
B
Step-by-step explanation:
x% of 6 = 5.25
x 6 = 5.25
= x
x = 87.5 %
discount = 100 - 87.5 %
= 12.5 %
