Question

Help me plz it will be on the exam! Pedro and Bobby each own an ant farm. Pedro starts with 100 ants and says his farm is growing exponentially at a rate of 15% per month. Bobby starts with 350 ants and says his farm is steadily decreasing by 5 ants per month.

Assuming both boys are accurate in describing the population of their ant farms, after how many months will they both have approximately the same number of ants?

Answer 1

After approximately 8.5 months they will have the same number of ants. But this answer is only approximate not exact, keep that in mind. The numbers that would be closer to exact (but not exact) would be 9 months for bobby and 8 months for pedro. because bobby would have 305 ants after 9 months and pedro would have 305.90228625390614 after 8 months. hope i helped.
