Answer:
The current price index number is $604.2.
Step-by-step explanation:
The index value is the ratio between the current value and the reference value, multiplied by 100.
In this problem, we have that:
Current value = $3.48
Reference value: $0.576
Index price = (3.48/0.576)*100 = $604.2.
The current price index number is $604.2.
