Problema Solution
Calvin has a wall safe that contains 219950.00. If it has 9 times as many 200-peso bills as 100-peso bills, and 5 times as many 50-peso bills as 200-peso bills, how many 200-peso bills does the wall safe have?
Answer provided by our tutors
Let 'x' represent the number of 200-peso bills, then 'x/9' represents the number of 100-peso bills and 5x represents the number of 50-peso bills.
219950=200x+100(x/9)+50(5x)
x=477
So 477 200-peso bills were contained in the wall safe.
