Kirk sent $54 to the newspaper dealer for whom he delivers papers after deducting a 10% commission for himself.
Total revenue earned = 54*100/90 = 60$

1$ = 100cents
60$ = 100*60
60$ = 6000 cents

If newspapers sell for 40 cents each, the number of newspaper sold = 6000/40 = 150

Answer is B

Let the total amount be X
Now, Kirk deducts 10% commission for himself.
So, \(54 = 0.9 \times X\)

\(X = 60$\)

The total amount collected is 60$ after selling the newspapers @ \(40\) cents/ newspaper = \(\frac{40}{100} $\) per newspaper

Number of newspapers sold = \( \frac{ 60}{0.4} = \frac{600}{4} = 150\)

OA, B

Solution


    • Let us assume that kirk delivered x papers.
      o So, total revenue from the sell of paper \(= $0.4x\)
    • He Kept 10% commission for himself and gave $54 to the newspaper dealer.
      o It means, 90% of \(0.4x = $54 ⟹ 0.9*0.4x = 54⟹ x = \frac{54}{0.36} ⟹ x = \frac{5400}{36}= 150\)
Thus, the correct answer is Option B.

.9x = 54
So, x = 60
Each paper price is 40 cent.
so, 60/.4 = 150
