When nutrients for a bacteria culture are exhausted, the bacteria culture goes through the death, or decay, phase of the bacteria growth curve. The following graph shows the number of living bacteria in the colony as a function of time, in hours, after the start of the decay phase. Determine the statement that correctly interprets the graph of the function.
A: There were 133,200 living bacteria in the culture at the start of the decay phase.
B: The number of living bacteria in the culture decreases by about 7.25% each hour.
C: The number of living bacteria in the culture decreases by about 26% each hour.
D:The number of living bacteria in the culture decreases by about 6.5% each hour.
