Which explicit equation represents her situation?

Stephanie is collecting data on the reaction of bacteria to different antibodies. She did not measure the area of the bacteria in the dish when she began the experiment but measured 20cm² of bacteria after 1 hour. She continued to measure the bacteria each hour and entered the data in the table.

What is the constant ratio in this sequence?

• 1.25

• -4

• .5

• .8
