If you bought 20 pounds of cashews, your bottom line would remain the same.

How many pounds of cashews should be mixed with the peanuts to ensure no change in the​ revenue?

Cashew and peanut butter together represent a linear relationship. Twenty pounds of cashews would have no impact on profits.

Cashews are represented here by the letter c and peanuts by the letter p.

U-4.00

Up=1.50

Um=2.00

p-40  pounds of peanuts that have not been sold.

m=40+c -when 40 pounds of peanuts are combined with cashews, the resulting combination

Generally, the equation for c is  mathematically given as

Ue x c+Up xp=Um x m

Therefore

4.00 x c+1.50 x 40 2.00 x (40+c)

4c+60-80+2c

2c= 20

c=10

In conclusion, If you bought 20 pounds of cashews, your bottom line would remain the same.
