Answer:
Step-by-step explanation:
in this problem we are expected to formulate the constraints
let chairs, loungers and footstools be x, y and z respectively
1. For wood we have
30x+25y+20z=1380
2 . For fabric we have
30x+15y+5z=890
. For stuffing we have
10x+10y+5z=450
therefore the three equation are
30x+25y+20z=1380
30x+15y+5z=890
10x+10y+5z=450
