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.
Answer:
She has 6 hours left.
Step-by-step explanation:
She started with 3 hours saved and got 2 more hours for each day that she did her chores and ate her vegetables. Since she did her chores and ate her vegetables 4 days that means that in total she gained 8 hours (4 * 2) plus the ones she already had saved. So 8 + 3 = 12 - 6 = 6
