Solve the problem.
-Suppose y = mx + b is a mathematical model for actual time as a function of estimated time, where y represents actual time and x represents estimated time and m and b are constants. If m = 3.5 and B = -2.1, what was the estimated time, x, if the actual elapsed time is 102.9 minutes?
A)30 min
B)102.9 min
C)358.05 min
D)367.5 min

Given y = mx + b, with y = 102.9, m = 3.5, and b = -2.1, solving for x gives x = (y - b) / m = (102.9 + 2.1) / 3.5 = 30.
