Stacy sells art prints for $12 each. Her expenses are $2.50 per print, plus $38 for equipment. Which system of equations represents Stacy's revenues (money earned) and expenses?

• Revenue: y = 12 + 2.5x

  Expense: y = 38

• Revenue: y = 12 + 38x

  Expense: y = 38

• Revenue: y = 12x

  Expense: y = 2.5x + 38

• Revenue: y = 12x

  Expense: y = 2.5 + 38x
