Answer:
$6.88
Step-by-step explanation:
We are trying to compare two options: Buying a magazine for 12 months or for just 1 year.
To solve this, we can multiply the monthly rate by 12 because there are 12 months in a year.
5.99 x 12 = 71.88
The other option is to just pay $65 dollars for a whole year (12 months).
Comparing the two options, we see paying for the whole year is cheaper than paying for each month individually. Because of this, we can subtract $65, the cheaper option, from $71.88 to get $6.88
Chris will save $6.88 by paying for the whole year instead of purchasing for each month.
