Suppose contact lenses cost $300 for a year’s supply or $30 for a month’s supply. Which is less expensive to order per year, paying for 12 months at one time or paying for 1 month at a time?(1 point)%0D%0A month(s) at a time
To find out which option is less expensive, we need to compare the total cost of each option over a year.
If you pay for a year's supply at one time, the cost would be $300.
If you pay for 1 month at a time, the cost would be $30 x 12 = $360.
Therefore, paying for a year's supply at one time is less expensive.
To determine which option is less expensive per year, let's calculate the cost of each option.
Paying for 12 months at one time:
The cost of contact lenses for a year's supply is $300.
Paying for 1 month at a time:
The cost of contact lenses for a month's supply is $30.
To find the cost per year when paying for 1 month at a time, we multiply the cost per month by 12:
$30/month * 12 months = $360 per year.
Comparing the two options, we see that paying for 12 months at one time is less expensive than paying for 1 month at a time. Therefore, it is cheaper to order contact lenses by paying for 12 months at one time.
To determine which option is less expensive, let's first calculate the total cost for each option.
Paying for a year's supply at one time:
The cost for a year's supply is $300.
So, paying for 12 months at one time would be 12 * $300 = $3600.
Paying for a month's supply at a time:
The cost for a month's supply is $30.
To determine the cost for a year, we multiply the cost per month by the number of months in a year:
$30 * 12 = $360.
Therefore, paying for a month's supply at a time costs $360 per year, while paying for a year's supply at one time costs $3600 per year.
Thus, it is less expensive to order contact lenses by paying for 1 month at a time.
