Introduction
In this article, we will delve into the world of mathematics and explore how to calculate the total cost of Evelyn's shopping spree. We will use a table to display the items she purchased and their respective costs. By applying basic arithmetic operations, we will determine the total amount Evelyn spent on her shopping trip.
The Shopping List
Evelyn spent the day shopping and made the following purchases:
| Item | Cost ($) |
|---|---|
| Camera | 66.31 |
| Hat | 13.44 |
| Parking | 8.00 |
| Planner | 9.78 |
Calculating the Total Cost
To calculate the total cost of Evelyn's purchases, we need to add up the costs of each item. We can do this by using the addition operation.
Step 1: Add the costs of the Camera and Hat
First, we will add the costs of the Camera and Hat.
66.31 + 13.44 = 79.75
Step 2: Add the cost of Parking to the previous total
Next, we will add the cost of Parking to the previous total.
79.75 + 8.00 = 87.75
Step 3: Add the cost of the Planner to the previous total
Finally, we will add the cost of the Planner to the previous total.
87.75 + 9.78 = 97.53
Conclusion
By applying basic arithmetic operations, we have calculated the total cost of Evelyn's shopping spree. The total cost of her purchases is $97.53.
