Tough and Tricky questions: Decimals.
The value of x is derived by summing a, b, and c and then rounding the result to the tenths place. The value of y is derived by first rounding a, b, and c to the tenths place and then summing the resulting values. If a = 5.45, b = 3.05, and c = 3.76, what is y – x? Choose the correct choice from the following answers.
A) -0.1	B) 0.4	C) 0.05	D) 0.1	E) 0
To find x, we first sum a, b, and c, then round to the tenths place. 5.45 + 3.05 + 3.76 = 12.26, which rounds to 12.2.   To find y, we first round a, b, and c to the tenths place and them sum them. so 5.4 + 3.0 + 3.8 = 12.2.   We are looking for y - x, which gives us  12.2 - 12.2=
