can somebody help me solve this word problem using piecewise function?


Utility bills


Situation: Jonathan hasn't paid his electricity bill for over a month and a week. He was warned for not paying his bill. He paid PHP 1,300 last month and only uses his TV, refrigerator, and computer, as well as charging his gadgets for electricity. If Jonathan used more electricity this time, he was charged PHP 1,661 and an additional PHP 100 if he delayed it for another week. 3 Problem Solutions:


A: Write a piecewise function that describes the electricity bill charges.



B: Meralco announced a discount event where bill prices are 15% off. If Jonathan's electricity bill is 1,661, what will be the price if it's 15% off?


C: What if Jonathan uses his computer for bitcoin mining that increases the amount of electricity consumed and can let him be charged 300 more php?​
