Step-by-step explanation:
this is a linear programming problem, and we are expected to draw up the linear program for the solution of the problem.
The objective function is
Maximize
35A+42B+20C=P
subject to constraints(board and wicker)
The constraints are
board
7A+5B+4C=3000
wicker
4A+5B+3C=1400
A>0, B>0, C>0
John is 31 and Jenny is 26
The answer is 30
You multiply 2 x 30 which is 60 and 60 + 30 = 90
hope this helps :D
255 litres for 340 km
for 1 km = 255/340 litres
for 100 km = 255/340 * 100 = 75 litres
