Ms. McDonald found that 5 out of 7 seeds produce corn. This means the success rate is 5/7 = 0.7142857 or approximately 71.43%.
To find out how many seeds she should plant to have 10,000 corn-bearing plants, we can set up a proportion:
5/7 = x/10,000
Cross multiplying:
7x = 5 * 10,000
7x = 50,000
x = 50,000 / 7
x = 7142.857
Since we can't plant a fraction of a seed, Ms. McDonald should plant 7143 seeds to have 10,000 corn-bearing plants.
