Real world equation: Sharon's restaurant is bringing in money from customers, and she needs to know how much she needs to pay off the bill for the electricity to run the place. To turn the electricity on, she has to pay $25. For every hour that the electricity is on for, she has to pay $4. How many hours can she have the electricity on for if she makes $49 profit?
I hope these helped! Not too sure about the last one, I sort of let me imagination run wild. In any case, don't hesitate to ask me questions if you have any further inquiries. <3
