Answer:
Abby need to spent 5 days on vacation to buy 20 postcards.
Step-by-step explanation:
Given:
Number of Postcard brought by Abby in 2 days of vacation = 8
Number of days of vacation = 2
We need find Number of days to spend on vacation to buy 20 Postcards
2 days = 8 postcards
1 day = Number of Postcard in 1 day
By using Unitary method we get;
Number of Postcard in 1 day =
Now we know that in 1 day he bought 4 Postcards So we need to find the Number of days to buy 20 postcards.

To my best understanding, you're given that
where <em>C</em>₁ and <em>C</em>₂ are some arbitrary paths, evidently starting at the point <em>P</em> and ending at the point <em>Q</em>, and you have to find the value of
where <em>C</em> is the path consisting of <em>C</em>₁ (from <em>P</em> to <em>Q</em>) and the reverse of <em>C</em>₂ (from <em>Q</em> back to <em>P</em>). So we have
40-(40x0.2)
original price minus twenty percent of this.
