Final answer:
Joan will pay for 1/4 of her prescription of 100 Theophylline capsules, which means she will purchase 25 capsules today.
Step-by-step explanation:
Joan has a prescription for 100 Theophylline capsules. If she can only afford to pay for 1/4 of the prescription today, we need to calculate how many capsules that would be. To find this, we can multiply the total number of capsules by the fraction of the prescription she is able to pay for:
- Total prescription = 100 capsules
- Fraction to pay for = 1/4
- Capsules to pay for = Total prescription × Fraction to pay for
- Capsules to pay for = 100 × 1/4
- Capsules to pay for = 25
Therefore, Joan will pay for 25 capsules today.
