If each number in the following sum were increased by t, the new sum would be 4.22. What is the value of t ?
A. 0.24 B. 0.29 C. 0.33 D. 0.37
Explanation: D To figure out how much you need to add to 2.74 to get to 4.22, take 4.22 − 2.74 on your calculator. The difference between the two numbers is 1.48. This increase reflects the same number, t, added to each of the four numbers on the list. Divide 1.48 by 4 to find that t = 0.37, which is (D).
