Question

The total weight of 30 bags of flour and 4 bags of sugar is 42.6 kg. if each bag of sugar weighs 0.75 kg, what is the weight of each bag of flour?

Answer 1

so.....4*0.75=3 kg
rest weight=39.6

so......weight of each bag of flour = 39.6/30=1.32 kg

Answer 2

x = weight of each bag of flour

30x + 4*0.75 = 42.6
30x + 3 = 42.6
30x = 39.6
x = 39.6/30
x = 1.32kg
