Explanation for Question 6 From the Math (No Calc) Section on the 2017 May Sat
Question six, we have a long paragraph. 2 And when I have a long paragraph, I like to circle the important parts 3 as I read the question. So get a pen so you can follow along. 4 It says the chef plans to cook a maximum maximum of 5 a hundred trays for a dinner party. 6 Each Andrei will include either chicken or fish. 7 The cost of ingredients for each chicken entry is seven. 8 And the cost for each fish entree is nine. 9 If no, more than 850 can be spent on ingredients for 10 the entries and the chef cooks seed chicken entries and F chicken entries, 11 which of the following systems best represents the constraints on C and 12 F. So our job here is to translate this paragraph into 13 a system of equations. We're going to have two equations, 14 one representing the number of Andres and two representing 15 the, um, the cost spent on both Andres or the 16 total amount cost. 17 So like I said, the first one is going to be representing the amount 18 of Andres. And we know that that's going to be a maximum of a 19 hundred entrees. So when it says maximum, 20 that means that it cannot exceed a hundred, 21 which means it's a hundred or less. So we're going to say a hundred 22 or whatever we have here is going to be less than or equal to 23 a hundred. Now let's see what we need 24 to add to equal to the 100 Andres. 25 So we know that they make chicken and fish, 26 and we know that C is chicken 27 and fish. So that being said, 28 we're only making chicken and fish. We're not making any...
