You can put this solution on YOUR website! you have $165 in ones, fives, and tens. there are three times as many $1 bills as $10 bills, and four times as many $5 bills than $10 bills. how many bills of each kind do you have?
Let x be the number of $10 bills. Then the number of $1 bills is 3*x and the number of $5 bills is 4*x.
So:
10*x + 1*(3*x) + 5*(4*x) = 165
10x + 3x + 20x = 165
Solve for x, then compute 3x and 4x.
