Algebraic Expression:streaming Service Charges A Monthly Subscription Fee Of Php 150 And An Additional Php 50 For A Family Plan Upgrade. If Someone Subscribe To The Family Plan For 3 Months, How Much Will Be The Total Costs?
Introduction
Algebraic expressions are a fundamental concept in mathematics that can be used to represent various real-world situations. In this article, we will explore how algebraic expressions can be used to calculate the total cost of a monthly subscription fee for a streaming service. We will also discuss how to calculate the total cost of a family plan upgrade for a specific period.
The Problem
A streaming service charges a monthly subscription fee of Php 150. If someone subscribes to the family plan, an additional Php 50 is charged. If someone subscribes to the family plan for 3 months, how much will be the total costs?
Breaking Down the Problem
To solve this problem, we need to break it down into smaller parts. Let's start by identifying the variables and constants involved.
- Monthly subscription fee: Php 150
- Family plan upgrade: Php 50
- Number of months: 3
We can represent the total cost as an algebraic expression:
Total Cost = (Monthly Subscription Fee + Family Plan Upgrade) x Number of Months
Simplifying the Algebraic Expression
Now, let's simplify the algebraic expression by plugging in the values:
Total Cost = (Php 150 + Php 50) x 3
Total Cost = Php 200 x 3
Calculating the Total Cost
To calculate the total cost, we need to multiply the simplified algebraic expression by the number of months:
Total Cost = Php 200 x 3 Total Cost = Php 600
Conclusion
In this article, we used algebraic expressions to calculate the total cost of a monthly subscription fee for a streaming service. We also discussed how to calculate the total cost of a family plan upgrade for a specific period. By breaking down the problem into smaller parts and simplifying the algebraic expression, we were able to arrive at the correct answer.
