A pressure gauge in a cannery reads 42.057 psi (pounds per square inch). If the desired reading is 42.05 psi with a tolerance of ±0.004 psi, is the gauge within the tolerance bounds? What is the tolerance range?
A)Yes; ±42.054 psi
B)Yes; 42.054 psi and 42.046 psi
C)No; ±42.046 psi
D)No; 42.054 psi and 42.046 psi

The tolerance range is from 42.05 - 0.004 = 42.046 psi to 42.05 + 0.004 = 42.054 psi. The gauge reading of 42.057 psi is outside this range, so it is not within the tolerance bounds.
