Olivia will have $177.50 in the end of five months after all fees.

this is what I would come up with because.
y=the number of people infected
x=the number of days that have passed
1/5x1/2=1/10
1/5 because there are 5 flavors.
1/2 because there are 2 kinds of pies.
So the answer is 1/10.
Hope this helps.
Can you restate the question please
