actually for the last question the answer is guessable because of the given options: option a and b are eliminated cause theyre less than 100% it cant be 2324 cause if u subtract c from b + c the percent will be more than 2x of 2241 so thats gotta be 4941 (ik its complicated and the options may not allow u to use this method especially if theyre so clost to each other but if it helps it helps)

in 3:03, why did you multiply 6/4 by its reciprocal?

Sorry if I didn't explain well enough in the video. Basically, if you raise anything to the 1st power it doesn't change right? So in order to JUST multiply by 1.04 and increase by 4%, we want to raise that 1.04 to the first power. Since the exponent wasn't 1, we want to change it to 1. How do you change any fraction into 1? Multiply by the reciprocal. Hope that helps clarify.

But how did you know that you had to multiply 12 with the reciprocal of 6/4 (4/6 or 2/3) to get the answer? Why couldnt you just multiply 6/4 with 12 which is what my first answer was?

@@strangevials1161​​⁠because were given that the population will increase by 4% every n months, we know that when (6/4)t=1, the population will increase by 4% (as we’re just multiplying the original population by 1.04). Solving (6/4)t=1, we get t=4/6 (ie every 4/6 years the population increases by 4%). However, t is in years and we are being asked for n months. So, we then multiply 4/6 years by 12 months/1 year to cancel the year units and get 8 months. By just multiplying 6/4 by 12, you are simply converting 6/4 from years to months, but not finding how many months it takes for the population to increase by 4%. You can visualize this by comparing P(0) to P(1.5), 1.5 years is the same as 18 months, and seeing that P(0)*1.04≠P(1.5)

Because 6/4 isn't 1. We needed that reciprocal to change it to 1.

hello, are these questiones taken from bluebook tests?

Oh, sorry about that. I'll make sure to mention it next time.

i have taken the may 4th Digital SAT and i have to admit that i have faced with these questions in first module not second, so maybe these questions could help you to reach 650 or 600 but not 700 I assume?

These types of tricks can show up up in either module. The specific ones I chose happen to exemplify the tricks well. Avoiding hasty mistakes can certainly help you get up to 700-as long as you also know the material.
