Sherry earns an hourly wage plus a bonus for each day’s work. she uses the equation 10.5h + 50 to represent the total amount she earns each day, where h is the number of hours she works. sherry uses the table below to show the amount she earns. what error did sherry make when completing the table? a. she did not start the table with 0 hours worked and $50 earned. b. she should not have added 50 when she calculated the amount earned for 1 hour. c. she added 10.5 and 50, then multiplied by 6 to calculate the amount earned for 6 hours. d. she should have added 10.5 and 60 before multiplying by the hours worked.

The biologist has a second culture to examine. she knows that the population of the culture doubles every 15 minutes. after 1 hour and 15 minutes, her assistant found that 80,000 bacteria were present. a) what was the size of the initial population? b) predict the size of the culture at t=3 hours. what was the size of the population at 40 minutes? explain and justify your answers. c) create a graph of the population as a function of time. find an equation that can be used to predict the size of the population at any time t. d) examine the rate at which the bacteria culture is growing. how fast is the culture growing after 1 hour? after 1.5 hours? after 2 hours? use a time interval of h = 0.01 hours to estimate these rates. interpret these rates in terms of the context of the problem situation. how do these three rates compare?
