Answer: 5X + 8Y >= 300; intersection at (-20, 50) Step-by-step explanation: let t = work hours 0 < t < 30 X = time lawn mowing Y = time babysitting. X + Y < 30 5X + 8Y >= 300 We could solve... X < 30 - Y 5(30 - Y) + 8Y >=300 150 - 5Y + 8Y >= 300 3Y >=150 Y >=50 then X < -20 intersection at (-20, 50)
