 @dwhite@qMONEY TUTORIAL -- PART 2. Here are some sample Money Problems involving coins with different values.&d(0,)@jThe WHOLE -- the value of all the coins -- is the sum of the PARTS -- the value of each of the coins. &d(0,Add the parts -- Nickels\, Dimes\, and Quarters -- together to get the whole -- the Total.)@dallcoin&c(20,Nickels + Dimes + Quarters)&d(0,Add the parts -- Nickels\, Dimes\, and Quarters -- together to get the whole -- the Total.)@dmixcoin&c(20,Nickels + Dimes + Quarters = Total)&d(0,Add the parts -- Nickels\, Dimes\, and Quarters -- together to get the whole -- the Total.)@dg01&d(1,Nickels)&c(2,Dimes)&c(3,Quarters)&c(4,Tot.)&d(5,Units)&d(10,Coins)&d(15,Value)&d(6,5 cents)&d(7,10 cents)&d(8,25 cents)&c(20, Nickels + Dimes + Quarters = Total)&d(0, )@jThe grid helps you organize information to solve this equation.
