since a nickel is worth 5 cents and there is ten nickels the equation for this is 5 x 10 and 5 x 10 = 50 so now that we know what the nickels are worth 50 cents we now know that there is a dollar and 50 cents left so the equation to find the answer would be $1.50 divide by 25 cents = 6 so to check your answer multiply 6 times 25 cents and you get $1.50 so the correct answer is 6 quarters.
