We have the LP:

MAX

$ 3 v + $ 2.5 c \$3 \cdot v + \$2.5 \cdot c

subject to:

v + c 90 ; v+c \le 90;

0.3 v + 0.2 c 24 ; 0.3v + 0.2c \le 24;

v , c 0 v,c \ge 0 .

The feasible region is the plot below:

which has the critical vertices ( c , v ) = ( 0 , 0 ) ; ( 0 , 90 ) ; ( 80 , 0 ) ; ( 30 , 60 ) . (c,v) = (0,0); (0,90); (80,0); (30,60). Plugging each of these points into the objective function, the maximum income occurs at ( c , v ) = ( 30 , 60 ) = $ 255 . \boxed{(c,v) = (30,60) = \$255}.
