Hi,
850 $ -- 6%*850 $ = 850 $ -- 6*850/100 $ = 850 $ -- 5100/100 $ = 850 $ -- 51 $ = 799 $.
Easy, huh ?

Answer:
(D)$2079.23
Step-by-step explanation:
If I borrowed $11,250 from the bank to buy a used car. You will pay the bank back in 5 years with 3.45% interest compounded annually, then:
Principal=$11,250
Time=5 years
Rate=3.45%
Since it is compounded annually, our compound interest will be derived using this formula:
Interest=Amount at the end of 5 years - Principal
where:
Amount, 

Therefore our Interest=13329.23-11250 =$2079.23
When multiplying fractions, multiply straight across:
(-3/7) (6/5) =
(-3 * 6) / (7*5)=
-18/35
The answer is B.
Answer:
sin(3π/7 - 2π/21)
Step-by-step explanation:
Given
sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21
Required
Write a trigonometry formula for the expression
Using sine formula, we have:
sin(A - B) = sinAcosB - cosAsinB
The above formula can be applied to the given expression where
A = 3π/7
B = 2π/21
So, the trigonometry formula is:
sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21= sin(3π/7 - 2π/21)
