If the original value of a car is $18,000, and it loses value by 15% each year, then you can calculate the new value of the car after n years using following formula:
When n=3, then
Answer: the value of the car after 3 years is $11,054.25.
I think the answer would be 11,054.25$
a - 6b + 4c
a - 10b + 4c
-a + 10b + 4c
Answer:
a-6b+4c
Step-by-step explanation:
a-{5b-[a-(3b-2c)+c-(a-2b-c)]}
a-{5b-[a-1(3b-2c)+c-1(a-2b-c)]}
a-{5b-[a+(-3b+2c)+c+(-a+2b+c)]}
a-{5b-[a-3b+2c+c-a+2b+c]}
a-{5b-[-b+4c]}
a-{5b+[b-4c]}
a-{5b+b-4c}
a-{6b-4c}
a+{-6b+4c}
a-6b+4c

Answer:
Step-by-step explanation:
You know that 9 = 10 - 1.
Then 9 of something is equal to 10 of it less one of it. Here, that "something" is four.

Comment on this math
This illustrates a shortcut for multiplying by 9 that can be convenient for mental arithmetic. The idea is to multiply by 10, which just involves adding 0 (or moving the decimal point), then subtract the original number.
