Answer:_______________

Answer: $325

SOLUTION 1 :

Step 1:	20-cent coins	→ 75%
	50-cent coins	→ 100%
	Difference	→ 100% - 75%
		= 25%
Step 2:	25%	→ 125	(difference)
	1%	→ $\frac{125}{25%}$
	75%	→ $\frac{125}{25%}$ x $\frac{75%}{1}$	(number of 20-cent coins)
		= 375
	100%	→ $\frac{125}{25%}$ x $\frac{100%}{1}$	(number of 50-cent coins)
		= 500
Step 3:	Amount of money in the bag	→ (375 x $0.20) + (500 x $0.50)
		= $325
