which offer(a or b ) is the best value for money?

Answer 1

Answer:

Offer b is the best value for money

Step-by-step explanation:

Average Value

To compare different offers of the same product, we often calculate the average value of each offer. Once we have all the values referred to a common base, we can compare and decide.

The shop is offering 2 bags of 25 Kg of fertilizer for £35 and 3 bags of 50 Kf of fertilizer for £92.50.

Since the number of kilograms per bag and the number of bags for each offer are not the same, we calculate the cost of each kilogram of fertilizer for each offer.

The first offer is for 2 bags of 25 kg, that is, 50 Kg of fertilizer. The cost of each kilogram is

£35/50 = £0.7

The second offer is for 3 bags of 50 Kg, that is, 150 Kg of fertilizer, which cost per kilogram is:

£92.50/150 = £0.62

Since the second cost per kilogram is less than the first one, offer b is the best value for money
