A population of amoebas in a petri dish will triple in size every hour. At the start of an experiment the population is 800. The function y equals 800 times 3 to the power of x, where x is the number of hours, models the population growth. How many amoebas are in the petri dish after 9 hours?

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:
