Question

rory sells t - shirts at a festival for $15 each. he pays $100 in materials and fees. rory’s profit after the festival is $350. he wants to know how many shirts he sold. 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: Isolate the term with $n$

Add 100 to both sides:
$15n - 100 + 100 = 350 + 100$
$15n = 450$

Step2: Solve for $n$

Divide both sides by 15:
$\frac{15n}{15} = \frac{450}{15}$
$n = 30$

Answer:

$n = 30$
