![]() Solving this set of equations is made easier if we divide both sides of the second equation by $10$. We now have a system of two simultaneous equations that we can use to solve for $s$ and $d$: The 4, slightly outdated official ACT practice test PDFs: ACT Practice Test 2014-15 (Form 67C) ACT Practice Test 2011-12 (Form 64E), which is the same as 2010-2011 2009-2010 ACT Practice Test 2008-09 (Form 61C), which is the same as 2007-2008 2006-2007 ACT Practice Test 2005-06 (Form 59F) Free Piqosity Answer Explanations. We can combine this information to get the following equation: Joe also leaves a 12 tip that he calculates based on his. The total cost of his food is 24.75, and then an 8 sales tax is added to this amount. Joe eats at the same restaurant every night and orders the same meal. For these questions the use of a calculator is allowed. Renting the dancing room for $d$ minutes cost $20d$. This practice test covers the second section of PSAT Math. Renting the singing room for s minutes cost $10s$. We also know that the total cost was $\$600$. We know that together the rooms were rented for a total of 48 minutes: Let $s$ be the number of minutes the singing room was rented, and let $d$ be the number of minutes the dancing room was rented. Something very helpful to realize in this question is that even though $b$ technically must be greater than $\frac$ False ![]() Using these facts, you can conclude that the correct choice is (A).Īn alternative approach is to find a value of $b$ that can be used to test each of the four answer choices. ![]() Similarly, when a fraction (less than 1) is taken to a negative power, the result will be greater than the original fraction. The sample math questions you’ll find here are brief samples designed to give you the insights you need to be as prepared as possible for your PSAT Math test. Thus $b$ will be greater than $b^n$ when $n>1$. Use the fact that multiplying a fraction (less than 1) by itself will make the result smaller each time.
