Question

Java code is calculating the bill wrong and not displaying currency at the end: I've highlighted the error in the cosole

Southwest Power and Light

Billing Statement

Please enter your name > J, P

Customer name:J, P

Meter reading date > 2/15/16

Meter reading date:2/15/16

Electricity used: >

225

The basic rate is:22.5

The totalBill is 225.0

Calculate another bill? (Y/N)?:

The correct answer should be baseline charge: $22.50 and total bill: $22.50

The Charges are based on these:

0kw - 350kw: basic rate

351kw - 500kw : 10% above basic rate
500kw > : 25% above basic rate

dates:
Basic rate Charges/ Varies by months       
$0.10 from 12/1 to 2/29
$0.12 from 3/1 to 5/31
$0.15 from 6/1 to 11/30
