The answer is 50 cents. Why? Well, when there’s 6 nickels (which make up 30 cents), there is a total of 40 cents. I noticed this pattern throughout all of the relationships. The total amount of coins is usually 10 cents more than how much the amount of nickels are worth. So, by using this strategy, we will find that there is 50 cents because 8 nickels is equal to 40 cents, which we can find by multiplying 8 by 5 since each nickel is worth 5 cents. The amount of nickels makes up 90% total of the quantity of coins altogether. Because 8 multiplied by 5 equals 40, we can add 10 to find that our total value of coins is 50 cents.

Your final answer: Your answer is B. If you need help, let me know and I will gladly assist you.
