To determine which subscription plan is least expensive on a per-year basis, we will calculate the unit price for each subscription option.
-
1-year subscription:
- Cost: $24.97
- Per-year cost: \( \frac{24.97}{1} = 24.97 \)
-
2-year subscription:
- Cost: $45.94
- Per-year cost: \( \frac{45.94}{2} = 22.97 \)
-
3-year subscription:
- Cost: $74.91
- Per-year cost: \( \frac{74.91}{3} = 24.97 \)
Now we summarize the per-year costs:
- 1-year: $24.97
- 2-year: $22.97
- 3-year: $24.97
The least expensive plan per year is the 2-year subscription at $22.97 per year.
