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 $d$: ![]() We can combine this information to get the following equation: Renting the dancing room for $d$ minutes cost $20d$. 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. 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. Don’t be disheartened about these questions! Mometrix has all you need to successfully prepare for the PSAT.The correct answer is (A).
