The Grade 8 class at Wheatly Middle School sold 77 boxes of greeting cards to raise money for the under privileged. This is 22% of all the boxes of greeting cards sold. Calculate how many boxes were sold.
77 / .22 = ?
0.22x = 77
To find the total number of boxes sold, we'll divide the number of boxes sold by the percentage.
Let's represent the total number of boxes sold as "x".
We know that 77 is 22% of the total number of boxes sold, so we can set up the equation:
77 = 0.22x
To solve for "x", we'll divide both sides of the equation by 0.22:
77 / 0.22 = x
Simplifying the left side of the equation:
350 = x
Therefore, the total number of boxes sold is 350.
To calculate the total number of boxes of greeting cards sold, we need to find the original quantity that 22% represents. Here's how you can solve this problem step by step:
1. Let's assume the total number of boxes of greeting cards sold is "x."
2. We know that 77 boxes were sold, which represents 22% of the total.
3. To calculate 22% of x, we can set up the following equation: 0.22x = 77.
- Since 22% is 0.22 as a decimal.
4. To find x, we need to isolate it on one side of the equation. To do this, divide both sides by 0.22: x = 77 / 0.22.
5. Now, let's calculate x: x = 350.
Therefore, a total of 350 boxes of greeting cards were sold.
