Answer:
Step-by-step explanation:
Let yesterday's price be x
Discount percentage = 36%
Sale price = $ 560
(100-36)% of x = 560
64 % *x = 560

Yesterday's price = $ 875
Step-by-step explanation:
You can set up a proportion.
Let x be the number of pencils needed.

Solve for x.
x = 9444.44 pencils (round it up to 9445 pencils if you need a whole number)
So what you do is theres 12 months so multiple that by 15 and get 180 then what you do is what time 80 equals 180 and thats your answer
