Jack has 10 nickels and some quarters. if the value of the coins is $2.00. how many quarts does he have?

Six quarters, which is equal to 1.50, and 1.50 plus .50 is equal to 2.

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.
