Hello tutor, help needed with the Calculus

A culture of bacteria in a particular dish has an initial population of 300 cells grows at a rate of N'(t) = 50 e 0.46210 cells/day. a. Find the population N(t) at any time t2 0. b. What is the population after 7 days? a. Find a formula for the number of cells, N(t), after t days. N(t) = (Round any numbers in exponents to five decimal places. Round all other numbers to the nearest tenth.)b. After 7 days, there are cells present. (Use the answer from part a to find this answer. Round to the nearest whole number as needed.)
