Suppose contact lenses cost $300 for a years supply of $30 for a months supply. Which is less expensive to order per year, paying for 12 months at one time or paying for 1 month at a time

Answer 1

To determine which option is less expensive, let's calculate the total cost for each option.

Paying for 12 months at one time:
The cost per year for contact lenses is $300.

Paying for 1 month at a time:
The cost per month for contact lenses is $30.
So, the total cost for 12 months would be $30 x 12 = $<<30*12=360>>360.

Comparing the costs:
The cost of paying for 12 months at one time is $300, while the cost of paying for 1 month at a time is $360.

Therefore, paying for 12 months at one time is less expensive since it costs $300, while paying for 1 month at a time costs $360.
