To calculate how much you and your friends spend on games in a year, we'll follow these steps:
- Determine how many times you buy games in a year.
- Calculate the total cost per purchase.
- Multiply by the number of purchases in a year.
Step 1: Number of Purchases in a Year
Since you buy games every four weeks, you can calculate the number of purchases in a year as follows:
- There are 52 weeks in a year.
- The number of purchases per year is: \[ \frac{52 \text{ weeks}}{4 \text{ weeks/purchase}} = 13 \text{ purchases/year} \]
Step 2: Total Cost per Purchase
The average cost of the games is $25. Since there are 5 friends, the cost per purchase for the group is: \[ 5 \text{ friends} \times 25 \text{ dollars/game} = 125 \text{ dollars/purchase} \]
Step 3: Total Annual Spending
Now you multiply the total cost per purchase by the number of purchases in a year: \[ 125 \text{ dollars/purchase} \times 13 \text{ purchases/year} = 1625 \text{ dollars/year} \]
So, you and your friends spend $1,625 on games in a year.
