She has a lot more fives and ones than tens, so let x be the number of tens. She has 3 times as many fives as tens, so she has 3x fives.Originally Posted by erickalittle
She has 5 times as many ones as fives, so she has 15x ones.
Now determine how much money she has in tens, fives and ones: E.g., x tens equals $10x.
Add up the total, and you get an expression involving x. Set this equal to 440, solve for x, then compute the number of fives and ones, and you are done.
