<p>It comes from PR's 11 practice tests. By the way, is it a good substitute if you want to save your real tests? Is it harder or easier? </p>
<p>"Admission to an amusement park costs $7 for a child and $15 for adult. If 96 tickets were sold for $800, what was the ratio of the number of adult's tickets sold to the number of children's tickets sold?"</p>
<p>They have 84 tickets for the adult, while I got 16
Whats your answer?</p>
<p>
</p>
<p>Two things …</p>
<ol>
<li><p>The wording (and spelling) of the problem and the proposed solution tells you all you need to do know about using non-ETS tests. They are pure garbage. </p></li>
<li><p>Your answer of 16 tickets at $15 (240) and 80 tickets at $7 (560) works. </p></li>
</ol>
<p>However, assuming the writer of that question knows what he wants, the answer should be in a ratio format. In this case, 16 to 80 is 1 to 5. But that is a HUGE assumption. </p>
<p>As a rule of thumb, you’’ want to ignore such tests. They are worthless and confusing.</p>
<p>Easily can be done with a system of equations.
7x+15y=800
x+y=96
Solve and you have the answer.
Once you solve for the number of adults and children, divide the number of adults by the number of children.</p>
