Answer: $1541

SOLUTION 1 :

Step 1:	20-cent coins	→ 85%
	50-cent coins	→ 100%
	Difference	→ 100% - 85%
		= 15%
Step 2:	15%	→ 345	(difference)
	1%	→ $\frac{345}{15%}$
	85%	→ $\frac{345}{15%}$ x $\frac{85%}{1}$	(number of 20-cent coins)
		= 1955
	100%	→ $\frac{345}{15%}$ x $\frac{100%}{1}$	(number of 50-cent coins)
		= 2300
Step 3:	Amount of money in the bag	→ (1955 x $0.20) + (2300 x $0.50)
		= $1541
