Greg is selling t-shirts for the baseball team as a fund raiser. the total amount earned for the team, y, is proportional to the number of t-shirts, x, greg sells. the team earns $7.50 for each sold t-shirt. which equation represents the total amount greg earns for the team?

y = $7.50x

y (total amount earned) is the dependent variable and x (number of t-shirts Greg sells) is independent.

y = kx → y = $7.50x

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
