Answer:
Stephen makes t-shirts. If he charges $30 for each t-shirt, his total revenue will be
$3,000 if he sells 100 t-shirts.
Step-by-step explanation:
The sales revenue is a product of the units sold and the price per unit. Since he sells 100 t-shirts, in this example, and charges $30 for each t-shirt, Stephen's total sales revenue will be $3,000 ($30 * 100). The other options do not add up correctly.
