Hi everybody! I am pretty close to finishing this program. It is supposed to calculate a person's energy use based on their past and current bill. I am stuck on the calculations and else/if statements. Thanks in advance for any feedback.

and ... what exactly are you stuck at?

here is the format of an if statement to get you started:

``````if(expression) {
} else if(expression) {
} else {
}``````

Not sure what is difficult about it

``if Rate < 500 then multiply by .0809``

should be just written as

``````if(Rate < 500){
calcUsage = calcUsage * 0.0809;
}``````

bur first you need to sort some errors you have before this
