Step-by-step explanation:
1. When it comes to budgeting like if we have upcoming event. We will figure out our total cost considering the number of visitors, the place, and the meal. If we will rent a place that cost P5000 and the price for food is P300 per person. A linear equation can be constructed to show the total cost, expressed as y for any number of attendees. The linear equation would be written as y = P300x + P5000. With this equation, we can substitute any number of guests and we can plan how much will be the actual cost of the event including meals and place rental.
2. In comparing of offered salary, linear equations can be a useful tool. If a company offered to pay P100 an hour and the other offers P3000 per week, and both companies work 40hours in a week, then which company is the best? A linear equation can help us solve this. The first company expressed as y = 100(40). The second is expressed as 3000 = 40x. After comparing, the first company offers more than the second by P1000 per week.
3, When we put gas to our car, if a liter of gas cost P80, and we only have P800 cash, how many liter of gas we can afford to buy? This can be expressed as 800 = 80x
