Contact lenses cost 300$ for a years supply or 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.
Paying for a year's supply at one time would cost $300, while paying for 1 month at a time would cost $30 per month, totaling $30 x 12 = $<<30*12=360>>360 per year. Thus, paying for a year's supply at one time is less expensive.
To determine which option is less expensive, let's calculate the total cost for each scenario:
1. Paying for a year's supply at once:
The cost for a year's supply is $300.
Therefore, the total cost for a year's supply is $300.
2. Paying for a month's supply at a time:
The cost for a month's supply is $30.
So, the total cost for a year's supply, paying monthly, is $30 x 12 = $360.
Comparing the two options:
- Paying for a year's supply at once costs $300.
- Paying for a month's supply at a time costs $360.
Therefore, ordering a year's supply and paying for 12 months at one time is less expensive than paying for 1 month at a time.
To determine which option is less expensive, let's calculate the total cost for each option:
Option 1: Paying for 12 months at one time:
The cost for a year's supply of contact lenses is $300. Since you'll be paying for 12 months at once, the total cost will still be $300.
Option 2: Paying for 1 month at a time:
The cost for a month's supply of contact lenses is $30. Since you'll be paying for 12 months individually, you'll need to calculate the cost for each month and then sum them up.
Cost for the first month: $30
Cost for the second month: $30
...
Cost for the twelfth month: $30
Sum of monthly costs: $30 + $30 + ... + $30 (12 times)
= $360
Comparing the options:
- Option 1 (12 months at one time): $300
- Option 2 (1 month at a time): $360
As we can see, paying for 12 months at one time is less expensive as it costs $300, while paying for 1 month at a time costs $360.
