Question

Amanda is earnings ($) vary directly with the number of ads she sells. if the situation can be represented by the equation y=5x how much money per ad does she sell

Answer 1

For her earnings to vary directly with the number of ads she sells, the y in your equation would represent the total amount of her earnings in dollars. The x would represent the number of ads she sells.

Therefore, the earnings per ad would be the 5 (or $5 earned for each ad sold). This is called the unit rate as well.
