To determine the number of tomato plants after 37 years, we can first figure out how many 4-year periods fit into 37 years.
First, calculate the number of 4-year periods in 37 years:
\[ \text{Number of 4-year periods} = \frac{37}{4} = 9.25 \]
Since we can only consider complete periods, we take 9 complete periods.
Next, we need to know how many tomato plants there will be after 9 periods of tripling. Since we start with 17 tomato plants, we can calculate the total number of plants after each period in terms of tripling:
After 1 period: \[ 17 \times 3^1 = 51 \]
After 2 periods: \[ 17 \times 3^2 = 17 \times 9 = 153 \]
After 3 periods: \[ 17 \times 3^3 = 17 \times 27 = 459 \]
After 4 periods: \[ 17 \times 3^4 = 17 \times 81 = 1377 \]
After 5 periods: \[ 17 \times 3^5 = 17 \times 243 = 4131 \]
After 6 periods: \[ 17 \times 3^6 = 17 \times 729 = 12483 \]
After 7 periods: \[ 17 \times 3^7 = 17 \times 2187 = 37179 \]
After 8 periods: \[ 17 \times 3^8 = 17 \times 6561 = 111573 \]
After 9 periods: \[ 17 \times 3^9 = 17 \times 19683 = 335109 \]
Thus, after 9 full periods (which is 36 years), there will be 335,109 tomato plants.
Now, we consider the next year (the 37th year). The problem states that the plants triple every 4 years, meaning that in the 37th year they won't complete another full tripling. Thus, we can treat the plant count from the 9th period as constant since it doesn't triple in that one additional year.
The final count of tomato plants after 37 years will still be:
\[ 335,109 \]
However, this does not appear in your provided options. If your result of plants being calculated is meant to be approximated for options provided, it should be noted that:
Given your provided multiple-choice answers, if you mean for the sake of simplification or rounding down:
- 440,372 (too high)
- 19 (too low)
- 28 (too low)
- 207 (too low)
Therefore, the methodology leads us to the result that it does not align with any of the available options directly. However, the closest theoretical calculation based on the tripling of tomato plants is 335,109 after 37 years.
