At Johnson Middle School, there are ﻿﻿﻿﻿﻿﻿500500﻿﻿﻿﻿﻿﻿ students in 7th grade and ﻿﻿﻿﻿﻿﻿575575﻿﻿﻿﻿﻿﻿ students in 8th grade. Next year, they are projecting that each class size will increase by ﻿﻿﻿﻿﻿﻿88﻿﻿﻿﻿﻿﻿%. What will be the total number of students at the school next year

To find the total number of students at Johnson Middle School next year after an 8% increase in both the 7th and 8th grades, follow these steps:

### Step 1: Calculate the increase for each grade

**7th Grade:**
\[
\text{Increase in 7th grade students} = \frac{8}{100} \times 500 = 0.08 \times 500 = 40
\]
\[
\text{New 7th grade size} = 500 + 40 = 540
\]

**8th Grade:**
\[
\text{Increase in 8th grade students} = \frac{8}{100} \times 575 = 0.08 \times 575 = 46
\]
\[
\text{New 8th grade size} = 575 + 46 = 621
\]

### Step 2: Add the new numbers of students in both grades
\[
\text{Total students next year} = 540 + 621 = 1161
\]

So, the total number of students at the school next year will be **1,161**.
