Test 7 Section 3 - #7 (page 770)

Variables in the question and in the answer?  I'm thinking PLUG-IN.  But we're not going to plug in directly for t here, we're going to plug in for the two numbers that differ by 1. Let's say our numbers are 2 and 3. So since t is the sum of those numbers, t = 5.

The question asks us for the greater of our two numbers, so we're looking for the answer that gives us 3, when we plug in t = 5.  Always try them all to be sure when you're plugging in, but the only one that works is going to be (C): plug in 5 for t and you end up with 6/2 = 3.
