3. Option A:
Option A
Assuming Ms. Reahl’s estimate is correct, she would have to supply 35
payments of $225, totaling $7875, $675 greater than if she chose option
D.
$225 x 35=$7875
But if her estimate is incorrect, and there are 31 or less snowfalls, then
option A would be the cheapest option. If there are more than 33
snowfalls, then option D would be cheapest. If there are 32 then option A
and option D would be equally expensive.
