Which of the following statements about the ncua is correct? a. the ncua is similar to the fdic, but it insures credit unions instead of banks. b. the ncua is an independent coalition of credit unions that works to protect investors. c. the ncua is the branch of the fdic that insures credit unions. d. the ncua controls the amount of money banks have available to lend out.

The correct answer is A

Step-by-step explanation:

NCUA : The National Credit Union Administration (NCUA) is the independent federal agency created by the United States Congress to regulate, charter, and supervise federal credit unions.

NCUA is not a branch of FDIC on the other hand it is independent coalition. Also, it works only to regulate and administrate federal credit union, not to protect its investors neither it controls available money for bank to lend out.

So, the only statement which is correct about NCUA is : The NCUA is similar to the FDIC, but it insures credit unions instead of banks.

step-by-step explanation:

30% of $420 is 0.30($420) = $126 and $420 + $126 = $546.

or, 130% of $420 is 1.3($420) = $546.

notice that this is not the $600 original list price with which we started.

why doesn't this work?

the method does not work because 30% of $420 is not the same amount as the 30% of $600. it may seem obvious when stated this way, but it is a very common error made on problems of this type. we cannot just use the same percent and get back to the original amount because we are taking that percent of a different value.

to work problems of this type correctly, it is generally best to write an equation for the situation and then solve.

example: since (100% – 30%)(original price) = (sale price)

70% of the   (original price) is $420.

0.7x   = 420

x = 600

the original cost was $600.

we may also solve this problem using the two-step method. working the problem in two steps requires us to use more algebra skills. we have to know that x = 1x (identity property of multiplicationtext annotation indicator) and that 1x – 0.3x = 0.7x (subtracting like terms). then we solve the problem as follows:

(original price) – 30%(original price) = sale price

x – 0.3x = 420

0.7x = $420

equation image indicator

x = 600

the original cost was $600.  

note that with both of the above methods we do obtain the correct original amount.

example: after a 5% pay raise, hermione is earning $22,680 per year. what was she earning before the pay raise?

105% of (original salary) = current salary

1.05x = 22,680

equation image indicator

x = 21,600

hermione earned $21,600 per year before the pay raise.

this is an example so maybe you will get how to at least do it!
