Suppose contact lenses cost 300 for a years supply ot 30 a month supply which is less expensive to order per year for 12 months at one time or paying 1 month at a tme

Answer 1

To determine which option is less expensive, let's compare the total cost of ordering contact lenses per year for each scenario:

1. Ordering a year's supply at one time: The cost is $300.

2. Paying 1 month at a time: The cost per month is $30. So the total cost for 12 months will be $30 x 12 = $360.

Comparing the two scenarios, we can see that ordering a year's supply at one time for $300 is less expensive than paying for 1 month at a time which amounts to $360 for the year.
