For the following, write the equation of the function and then use the equation to answer the question

b. The number of ants in a colony is increasing 15% per day. If there are 220 ants to start, how many will there be after one week?

d. There is 1 bacteria cell in a petri dish. Bacteria reproduce by dividing into two new cells. If this happens every hour, how many bacteria would be in the petri dish by the end of one day?

The burning of fossil fuels (oil, coal, and natural gas) releases carbon dioxide into the atmosphere. Carbon dioxide is known as a greenhouse gas because it tends to trap heat in the atmosphere causing global warming. In 1995, the United States emitted about 1.4 billion (1400 million) tons of carbon dioxide into the atmosphere. China was second largest contributor, emitting 850 million tons. US emissions were increasing at 1.3% a year, while Chinese emissions were increasing at 4% a year.

a. Make a table of values to show the carbon dioxide emissions of each country over the years. Copy and paste the table. What are the carbon dioxide emissions of the US and of China this year?

b. According to the table, in what year will carbon dioxide emissions in China exceed those in the US? (You may need to extend the table you made for part a)
