Answer: $256

SOLUTION 1 :

Step 1:	20-cent coins	→ 70%
	50-cent coins	→ 100%
	Difference	→ 100% - 70%
		= 30%
Step 2:	30%	→ 120	(difference)
	1%	→ $\frac{120}{30%}$
	70%	→ $\frac{120}{30%}$ x $\frac{70%}{1}$	(number of 20-cent coins)
		= 280
	100%	→ $\frac{120}{30%}$ x $\frac{100%}{1}$	(number of 50-cent coins)
		= 400
Step 3:	Amount of money in the bag	→ (280 x $0.20) + (400 x $0.50)
		= $256
