alternatively, (0.05 x 2000)+(0.045x8000)+(0.04x15000) = 1,060

Hope it is clear.

A. $1250 B.$1060
C. $1350 D.$900
E. $1000 30 sec approach - solve it using approximation 25000 sheet at full price, 5 cent = 1250 25000 sheet at max discount price, 4 cent = 1000 Your ans got to be between these two. Ans B it is. _________________ Lets Kudos!!!
