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 = 5.43, b = 2.98, and c = 3.76, what is y – x?
Choose the correct choice from the following answers
A) 0 B) 0.04 C) 0.05 D) 0.1 E) 0.2
To find x, we first sum a, b, and c, then round to the tenths place. 5.43 + 2.98 + 3.76 = 12.17, 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=
