Explanation for Question 7 From the Math (Calc) Section on the 2019 April Sat
All right. So number seven is one of the ones where it gives you 2 a number and asks you to interpret it in the context. 3 So for this question, it says Raymond's weekly income consists of a base salary 4 for a 40 hour work week. Plus overtime pay the overtime, 5 pays, paid at an hourly rate for the time that Raymond works. 6 In addition to his 40 hour work week, 7 Raymond's weight, weekly income in dollars can be represented by the expression 800 8 plus 30 X, where X is the total number of hours. 9 Raymond works over 40 hours, which of the following is the best interpretation of 10 the number 800 in this context. 11 So if we look at this function that it gives us here, 12 the 800 is con is constant. 13 The X is attached to the 30 here. So we know that the 800 14 is isn't going to change no matter what, you're always just going to be 15 adding those $800. 16 So we look back at this original sentence. 17 It tells us that his income consists of a base salary. 18 Plus overtime pick since overtime pay depends on how many hours you work. 19 We know that that corresponds with the 30 X. 20 So the 800 has to be the base salary. 21 So that is answer choice a.
