Final answer:
To determine how many teaspoons the parent should administer, we need to convert 7.5 mL of Cipro to teaspoons.
Step-by-step explanation:
To determine how many teaspoons the parent should administer, we need to convert 7.5 mL of Cipro to teaspoons. Since 1 teaspoon is approximately 5 mL, we can set up a proportion:
1 teaspoon / 5 mL = x teaspoons / 7.5 mL
By cross multiplying and solving for x, we find that the parent should administer 1.5 teaspoons (option b).
