Question

a) let n equal the number of shirts sold. which equation represents the situation?
15n - 100 = 350
solve the equation to find n, the number of shirts rory sold.
n = \boxed{}

Explanation:

Step1: Add 100 to both sides

To isolate the term with \( n \), we add 100 to both sides of the equation \( 15n - 100 = 350 \). This gives us \( 15n - 100 + 100 = 350 + 100 \), which simplifies to \( 15n = 450 \).

Step2: Divide both sides by 15

Now, to solve for \( n \), we divide both sides of the equation \( 15n = 450 \) by 15. So, \( \frac{15n}{15} = \frac{450}{15} \), which simplifies to \( n = 30 \).

Answer:

\( n = 30 \)
