WebJun 14, 2024 · We then plug in our particular plant size of 30 cm and do the math. First multiplication: (number of seeds) = 10 ∗ 30 + 15. Then addition: (number of seeds) = 300 + 15. (number of seeds) = 315. So, if the equation (number of seeds) = 10 * (plant size) + 15 is accurate, a plant that is 30 cm tall would produce 315 seeds.
