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?

30 bags of flour + 4 bags of sugar = 42.6 kg
each bag of sugar weighs 0.75 kg
each bag of flour weighs x kg = ?

If you would like to know what is the weight of each bag of flour, you can calculate this using the following steps:

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

Result: Each bag of flour weighs 1.32 kg.
