<p>What’s the most effective thing to do one day before the actual SAT?
Should i do another full test? Should i simply rest watch tv, ect.? </p>
<p>Also, any tips for the essay portion of the SAT?
How do u get a good score, aside from the fact that all 2 pages have to be filled in and that it has to be historical, and literary novels?</p>
<p>Thanks.</p>
<p>oh cool! alright what i did is this: </p>
<p>In essence this is a weighted average question. if you were to divide the total value of the 90 tokens (1275) by 90 you would get the approximate value of each token.</p>
<p>1275/90 = 14.17 This shows that majority of the tokens have a value of 15 since the average is leaning more to 15 (the scale, so to speak, is leaning more to 15, so there are a lot more 15pt tokens than 10pt). So i immediately looked for the highest possible number of 15pt tokens available i.e 75 </p>
<p>if 75 tokens have value of 15 then the remainder, 15, have a value of 10. so the total value of the tokens would equal (75<em>15)+(15</em>10) = 1275</p>
<p>so 75 is the answer! hope this was clear. This took me less than a minute to solve</p>
<p>hmm i think you’ll benefit greatly from reading this if you haven’t done so already: </p>

<p>Although the above trick method yields the answer quickly, I always get confused unless I can solve a question using plain old algebra. So here’s what I do:</p>
<p>Say there are T 10-point tokens and F 15-point tokens.</p>
<p>T+F=90 (As given)
10<em>T+15</em>F=1275 (Given, too)
Now T= 90-F
Put this in the second equation, which then becomes:
10<em>(90-F)+15</em>F=1275, and you get the answer.</p>
<p>canhazphysics’ approach would yield a more precise and undoubted answer efficiently. If I were you JohnLee, I’d utilize canhazphysics’ method. Not to mention that these types of questions are very very common in SAT Math.</p>
