insens350 [35]

Answer:

The correct answer is OB.

Step-by-step explanation:

Let us recall the Associative Property of Addition: given three real numbers a, b and c the following equality holds:

(a+b) + c = a+(b+c).

Let us remark that the Associative Property of Addition tells us that we can perform the sums in any order.  So,

(n+2)+7 = n+(2+7).

In the other options there was used the Commutative Property of Addition.

Kisachek [45]

A person sold 100 shares of a stock at a loss of 40%.

selling price for the 100 shares was $3,000

Let the stock was bought at $x then we can write

x-\frac{40x}{100}=3000\\ \\ \frac{100x-40x}{100}=3000\\ \\ \ \frac{60x}{100}=3000\\ \\ \ 60x= 3000*100\\ \\ x=\frac{3000*100}{60} \\ \\ \ x=5*100=5000\\

Hence Amount paid for the Stock was $5000
