8%﻿﻿. What will be the total number of 7th and 8th grade students at the school next year?

To determine the total number of 7th and 8th grade students at Johnson Middle School next year, we need to calculate the 8% increase for each grade and then add the results together.

### Step-by-step solution:

1. **Number of 7th grade students next year**:
   \[
   \text{New 7th grade students} = 500 + (500 \times 0.08) = 500 + 40 = 540
   \]

2. **Number of 8th grade students next year**:
   \[
   \text{New 8th grade students} = 575 + (575 \times 0.08) = 575 + 46 = 621
   \]

3. **Total number of students next year**:
   \[
   \text{Total students} = 540 + 621 = 1161
   \]

Thus, there will be a total of **1,161 students** in 7th and 8th grade at Johnson Middle School next year.
