Explanation for Question 4 From the Math (No Calc) Section on the 2019 May Sat
Question four says turns his car contains eight gallons of fuel. 2 He plans to drive the car and miles to using the fuel currently in 3 the car. If the car can drive 20 miles per gallon of fuel, 4 which inequality gives the possible values of X. 5 So the first thing we need to do is we need to find what 6 information is important in this paragraph. 7 So we know that the cars eight gallons of fuel so eight and 8 that it can drive 20 miles per gallon. 9 So if we want to find how many miles that the car can drive 10 or M we need to multiply eight times. 11 So now we've narrowed it down to a and B, 12 but the question is, is M greater than equal to, 13 or less than an equal to eight times 20. 14 So to find that out, we just need to look back at the problem 15 and realize that eight times 20 produces the maximum amount of miles that the 16 car can drive. The car could drive less than that amount based on the 17 amount of fuel it has. Uh, but it would run out of fuel if 18 it drove more than that. So the miles are going to be less than, 19 or equal to eight times 20. And so the answer here is.
