The answer is 7.50X =y because he sells each shirt for 7.50 than you times that to the amount of shirts he sold but we don’t know that amount so X will stand for the amount of shirts sold than 7.50 times X = Y and Y = the amount earned
Answer:

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