Show working bit by bit
To calculate the savings per kg by buying the 20kg sack of salt, we first need to find the cost per kg of the 250g packet of iodised salt.
The cost of the 250g packet of iodised salt is N150. To find the cost per kg, we can use the following formula:
Cost per kg = (Cost of 250g packet / 250g) x 1000
Cost per kg = (N150 / 250g) x 1000
Cost per kg = N0.6 x 1000
Cost per kg = N600
Now that we have the cost per kg of the 250g packet of iodised salt, we can find the savings per kg by buying the 20kg sack of salt.
The cost of the 20kg sack of salt is N10,400. To find the savings per kg, we subtract the cost per kg of the 250g packet from the cost per kg of the 20kg sack:
Savings per kg = Cost per kg of 250g packet - Cost per kg of 20kg sack
Savings per kg = N600 - (N10,400 / 20kg)
Savings per kg = N600 - N520
Savings per kg = N80
Therefore, the savings per kg by buying the 20kg sack of salt is N80.
