Phytoplankton are microscopic plants that live in the ocean. Phytoplankton grow abundantly in oceans around the world and are the foundation of the marine food chain. One variety of phytoplankton growing in tropical waters is increasing at a rate of 8% per month. If it is estimated that there are 80 million in the water, how many will there be in 7 months? Utilize formula N = N₀e^rt, where N represents the population of phytoplankton. Round to the nearest million. A) 290 millions B) 140 millions C) 4,480 millions D) 20 millions

Using the formula N = N₀e^(rt), where N₀ = 80 million, r = 0.08, and t = 7, we calculate N ≈ 80e^(0.08*7) ≈ 80e^0.56 ≈ 80 * 1.75 ≈ 140 million.
