Sue has $1.75 in quarters, dimes, and nickels. She has the same number of quarters and dimes. The dimes are worth $0.40 in all.

How many coins are dimes and quarters? Explain

What is the total value of the nickels? Justify your answer.

Write and solve an equation to determine how many nickels sue has.

So - we know that $0.40 is equal to 4 dimes. So that means that there must be 4 quarters, because it says that she has the same number of quarters and dimes. Next, 4 quarters equal $1.00, so $1.00 + $0.40 is $1.40. She has $1.75, and so then we need to subtract $1.40 from $1.75. The equation to find out the value of nickels is $1.75 - $1.40. That equals $0.35.
