Answer: $62

SOLUTION 1 :

Step 1:	20-cent coins	→ 60%
	50-cent coins	→ 100%
	Difference	→ 100% - 60%
		= 40%
Step 2:	40%	→ 40	(difference)
	1%	→ $\frac{40}{40%}$
	60%	→ $\frac{40}{40%}$ x $\frac{60%}{1}$	(number of 20-cent coins)
		= 60
	100%	→ $\frac{40}{40%}$ x $\frac{100%}{1}$	(number of 50-cent coins)
		= 100
Step 3:	Amount of money in the bag	→ (60 x $0.20) + (100 x $0.50)
		= $62
