On the 10th day, the person will wear 8 hours
Step-by-step explanation:
- Step 1: Given the person wears contact lenses for 3 hours on the 1st day and 0.5 hours every succeeding day. Form an equation for this.
Number of hours that the person wears contact lenses = 3 + 0.5 × n, where n is the respective succeeding day
⇒ Number of hours on the 10th day = 3 + 0.5 × 10 = 3 + 5 = 8
