Scenario 1: Calculating the cost of groceries
You are planning to go grocery shopping and need to calculate the total cost of your purchases. You know the price of each item you want to buy, and you know how many of each item you want to buy. You can use basic arithmetic to calculate the total cost of your groceries.
For example, if you want to buy 3 apples at $1.00 each, 2 bananas at $0.50 each, and 1 orange at $0.75 each, the total cost of your groceries would be:
3 apples * $1.00/apple + 2 bananas * $0.50/banana + 1 orange * $0.75/orange = $4.75
Scenario 2: Calculating the best gym membership
You are considering joining a gym, but you are not sure which membership is the best value for your money. You know the monthly cost of each membership, and you know how many times you plan to visit the gym each month. You can use basic algebra to calculate the total cost of each membership over a period of time.
For example, if the monthly cost of a basic membership is $20, the monthly cost of a premium membership is $30, and you plan to visit the gym 10 times per month, the total cost of each membership over a year would be:
Basic membership: 12 months * $20/month = $240
Premium membership: 12 months * $30/month = $360
As you can see, the premium membership is more expensive than the basic membership, but it would save you money if you plan to visit the gym more than 12 times per year.
These are just two examples of how basic arithmetic and algebra can be used to solve real-world quantitative problems. There are many other ways that these skills can be used in everyday life, such as when budgeting, tracking expenses, and calculating interest rates.
