Ms. Black has one begonia plant. If she buys two begonia plants each year for every one she has, how many will she have in four years?
She will have 16 plants. Hope this helped.
No wait that's wrong, the actual answer is 27.
The informer -- your answers are not correct.
Now - 1 begonia
after 1 year = 1 + 2 = 3
2 years = 3 + 6 = 9
3 years = 9 + 18 = 27
4 years = 27 + 54 = 81
5 years = 81 + 162 = 216 plants
Problem is 81+162 is not 216 it's 243
Well, let's do some clown math, shall we? If Ms. Black has one begonia plant and she buys two more each year for every one she has, we can break it down like this:
Year 1: One plant + two plants (she bought) = 3 plants
Year 2: 3 plants + (2 plants x 3) = 9 plants
Year 3: 9 plants + (2 plants x 9) = 27 plants
Year 4: 27 plants + (2 plants x 27) = 81 plants
So, after four years, Ms. Black will have a whopping 81 begonia plants! That's a whole lot of begonias. Good luck finding space for all those plants, Ms. Black! 🌱🌱🌱
To figure out how many begonia plants Ms. Black will have in four years, we need to first determine how many plants she has each year, taking into account the number of plants she buys.
From the given information, we know that she starts with one begonia plant.
In the first year, she buys two plants for every one she already has. So, if she starts with one plant, she buys 2 * 1 = 2 plants. Adding this to the initial plant, she will have a total of 1 + 2 = 3 plants at the end of the first year.
In the second year, she again buys twice the number she has at the beginning of the year. Since she now has three plants, she buys 2 * 3 = 6 plants. Adding this to the plants from the previous year, she will have a total of 3 + 6 = 9 plants by the end of the second year.
Similarly, in the third year, she will have 9 plants to start with and will buy 2 * 9 = 18 plants. Adding this to the plants from the previous year, she will have 9 + 18 = 27 plants by the end of the third year.
Finally, in the fourth year, she will have 27 plants to start with and will buy 2 * 27 = 54 plants. Adding this to the plants from the previous year, she will have 27 + 54 = 81 plants by the end of the fourth year.
Therefore, Ms. Black will have 81 begonia plants in four years.
