[Video] Q2: One of the requirements for becoming a court reporter is the ability to type 225 words per minute. donald can currently type 180 words per minute, and believes that with practice he can increase his typing speed by 5 words per minute each month. which of the following represents the number of words per minute that donald believes he will be able to type m months from now?

Explanation for Question 2 From the Math (Calc) Section on the Official Sat Practice Test 4

Now here in number two, we're trying to figure out an equation that can 2 be shown to get someone's ability to type 225 words per minute. 3 Right? We're talking about Donald who can originally type 180 words per minute. 4 And so that's like our starting point. And then from there, 5 Donald is able to increase his typing speed by five words per minute, 6 every month. So the 180 is our starting point, 7 but each month, right? Um, we're going to be able to increase that by 8 five by five words, which is why we'd want to add that to our 9 original starting point of 180. And so we see that here in answer choice 10 C. Now a has the reverse a has our starting point at five, 11 but we know we're not increasing 180 every month. 12 And so a essentially has the numbers reversed. 13 Now B has the wrong starting point because 2 25, 14 it's going to be how we want to end, but we must remember that 15 Donald started typing 180 words per minute, 16 and now what's wrong with these that we're subtracting the five words per minute, 17 which would mean that the time was getting slower, not faster. 18 And so our best answer then is C.
