10% of 50 coins is/are 5 coins.  So, 5 coins are pennies.


40% of 50 coins is/are 20 coins.  So, 20 coins are dimes.


The number of nickels is  (5 + 9) = 14, according to the condition.


Then quarters are the rest (50 - 5 - 20 - 14) = 11 coins.


Now you can easily calculate the total and answer the question


    Total = 5*1 + 14*5 + 20*10 + 11*25 = 550 cents = $5.50.     ANSWER

Solved.
