Answer: C
If x = 1- 3t and y = 2t - 3, then for what value of t does x = y?
Choose the most appropriate option:
A) 5/2  B) 3/2  C) 4/5  D) 2/5  E) 0

Solution: We are given x = 1 – 3t and y = 2t – 3, and we need to determine the value for t when x = y. We should notice that both x and y are already in terms of t. Thus, we can substitute 1 – 3t for x and 2t – 3 for y in the equation x = y. This gives us:   1 – 3t = 2t – 3   4 = 5t   4/5 = t   The answer is 4/5.

What is the average (arithmetic mean) of all multiples of 10 from 10 to 100 inclusive?
Choose the correct choice from the following answers:
A) 190	B) 195	C) 200	D) 205	E) 55

Solution: This question can be solved with the Average Formula and 'bunching.'   We're asked for the average of all of the multiples of 10 from 10 to 100, inclusive.   To start, we can figure out the total number of terms rather easily:   1(10) = 10   2(10) = 20   ...   10(10) = 100   So we know that there are 10 total numbers.   We can now figure out the SUM of those numbers with 'bunching':   10 + 100= 
10 + 100 = 110
110   20 + 90= 
20 + 90 = 110
110   30 + 80= 
30 + 80 = 110
110   Etc.   Since there are 10 total terms, this pattern will create 5 'pairs' of 110.   Thus, since the average= (Sum of terms)/(Number of terms), we have...   (5)(110)/(10) =55   Answer : 55
