Explanation for Question 1 From the Math (No Calc) Section on the 2019 March Sat
Question one says Tony spends $80 per month on public transportation, 2 a 10 ride pass cost 1250 and a single ride pass cost. 3 One 50. If G represents the number of 10 ride passes, 4 Tony buys in a month and T represents the number of single ride passes. 5 Tony buys in a month, which of the following equations best represents the relationship 6 between G and T. So I think what's helpful to start here is to 7 mark up on in this paragraph, 8 which variables and numbers go together. So I'm going to start with 80. 9 I'm gonna draw a square around this because that's the total. 10 So I know it's not going to be next to a variable. It's going 11 to be on the right side of the equation by itself. 12 And I'm going to circle 10 ride pass and 1250, 13 because the 10 ride passes cost 1250 and I'm going to circle, 14 um, GE because GE represents the number of 10 15 ride passes. Next I'm going to draw a triangle around 16 single ride pass and one 50, 17 because that, uh, the single ride passes cost one 50 and finally 18 around the variable T because I know that that variable rep represents single ride 19 passes. So now that they're marked up the past, 20 like this, it's really easy to see visually which variables in which numbers should 21 go together. So I know that this is going to be 1250 G 22 plus one 50 T 23 is equal to 80. 24 And so from that, I know that the answer is D.
