Explanation for Question 17 From the Math (Calc) Section on the 2018 May Sat
Question 17 says Emma, most grass at a constant rate of 1.5 2 acres per hour. She most two acres before lunch and plans to spend T 3 hours mowing after lunch. If Emma wants to mow at least eight acres of 4 grass today, which of the following inequalities best represents the situation. 5 So we know that she wants to moat at least eight acres, 6 which means that our equation needs to be greater than or equal to eight. 7 And we know that she's mowing 1.5 acres per hour, 8 but this equation isn't done because she already mode two acres, 9 which means that we need to add two to whatever she Moe's after lunch. 10 So our final equation is 1.5 T plus two is greater than or equal 11 to eight, which is answer choice.
