Let's break this down step by step.
From the grid description you provided, it appears that there are a total of 10 squares (3 shaded and 7 unshaded). Here's the information we need to fill in:
- Total squares: The grid has 10 total squares.
- Copies of the grid needed to have 100 total squares: Since each grid has 10 squares, Jordan needs \( \frac{100}{10} = 10 \) copies of the grid.
- With that many copies of the grid, the 3 shaded squares will become: Since there are 10 copies of the grid and 3 shaded squares in each grid, the total number of shaded squares will be \( 3 \times 10 = 30 \).
- So, of Jordan’s band friends play the saxophone: There are 10 friends in total and 30 shaded squares represent those who play saxophone. Thus, the percent of Jordan's band friends who play the saxophone is \( \frac{30}{100} \times 100% = 30% \).
So here's the final summary in a structured format:
- The grid has 10 total squares.
- Jordan needs 10 copies of the grid to have 100 total squares.
- With that many copies of the grid, the 3 shaded squares will become 30.
- So, 30% of Jordan’s band friends play the saxophone.
