from 1) 20(2p) - 20(c) = 2400 insufficient

from 2) 20(p+2) - 20(c)= 440 insuffecient

Combo:

solve for p and substitute in one of the equations to get C .

IMO C

Really, we can ignore the "20".

Profit = sale price - cost
Profit = revenue - cost
P = R - C

The question wants us to figure out R - C

Statement One:

20*(2R) - 20C = 2400

2R - C = 120

Can't determine R - C

Insufficient.

Statement Two:

20(R + 2) - 20C = 440

20R + 40 - 20C = 440

20R - 20C = 400

R - C = 20

The second statement is independently sufficient.

Choose B.
