Let x be the number of 5 kg packets of flour and y be the number of 2 kg packets of flour.
The total weight bought is 67 kg so we write:
The total cost is $38.50 so we write:
Solve the system by elimination. I decided to eliminate y. Multiply (1) by 2.5 to obtain (3):
Multiply (2) by 4 to obtain (4):
Subtract each side of (3) and (4) to eliminate y and solve for x:
Solve for yy using (1):
So, you bought 9 packets of 5 kg flour and 11 packets of 2 kg flour.
