Final answer:
Ted planted 8 pumpkin seeds, Ted can plan on growing 420 plants if he plants 560 seeds. The correct answer is A) 420 plants.
Step-by-step explanation:
To find out how many plants Ted can expect to grow if he plants 560 seeds, we can use the information about the number of sprouted seeds out of the 8 planted seeds. Ted planted 8 seeds and only 6 sprouted. This means that 6 out of 8 is the same as 3 out of 4.
To find out how many plants Ted can expect to grow if he plants 560 seeds, we can set up a proportion:
3/4 = x/560
By cross multiplying, we get: 4x = 3 * 560
Dividing both sides by 4, we find that x, or the number of sprouted plants out of 560 seeds, is 3 * 560 / 4 = 420 plants.
Therefore, the correct answer is A) 420 plants.
