Why is algebra important in High School to College?
In: 0
Algebra is used to model many normal things you need to think about. For example, let’s say you’re going to an amusement park. The fictional entrance fee is $50, and that gets you access to a basic set of activities, but there are premium activities that cost $10 each. Your budget for the excursion is $100. How many premium activities can you participate in? In algebra, that would be something like
total_budget = entrace_fee + premium_fee * premium_count
We also know that
total _budget = $100
entrance_fee = $50
premium_fee = $10
With these four equations, we can substitute and solve them using algebra and discover that we can go on 5 premium activities. This example is deliberately simple, but it is meant to show how algebra comes up normally.
Another examples might be: I have a certain amount of credit card debt, that accrues at a specific annual interest rate calculated monthly, and I can only pay this amount. How long will it take me to pay it off? How much will I end up paying to get rid of that balance?
