One pound is equivalent to 16 ounces.
Thus, multiply 14 pounds with 16 to get the number of ounces.
14 pounds equals 224 ounces. Let me know if you need any clarifications, thanks!

There are 5 pennies in a nickel, and 10 pennies in a dime. Now in $3.90 there are 390 pennies.
n = number of nickels in the pile
d = number of dimes in the pile
we know the pile has 55 coins, therefore whatever "n" and "d" are, we know that n + d = 55.
now, "n" is how many nickel coins are there, how many pennies is it in total? well, 5 pennies to a nickel, for "n" nickels, will then be 5(n) or 5n.
and "d" is how many dime coins are there, so therefore in "d" coins, there are 10(d) pennies, or 10d.
we also know the total amount of pennies is 390, therefore 5n + 10d = 390.
how many nickel coins are there anyway? well, n = 55 - d.
n = number of nickels in the pile
d = number of dimes in the pile
we know the pile has 55 coins, therefore whatever "n" and "d" are, we know that n + d = 55.
now, "n" is how many nickel coins are there, how many pennies is it in total? well, 5 pennies to a nickel, for "n" nickels, will then be 5(n) or 5n.
and "d" is how many dime coins are there, so therefore in "d" coins, there are 10(d) pennies, or 10d.
we also know the total amount of pennies is 390, therefore 5n + 10d = 390.
how many nickel coins are there anyway? well, n = 55 - d.
