Respuesta :

The units price are:

  • For brand A: $0.0796
  • For brand B: $0.0926

Then brand A is the better option.

How to find the unit price?

If you know that a set of N items has a price P, then the unit price is given by the quotient between the price and the number of items that you get, N.

For Brand A, we know that there are 25 spoons for $1.99, then in this case the unit price is:

a = $1.99/25 = $0.0796

For Brand B the set has 42 spoons for $3.89, then the unit price is:

b = $3.89/42 = $0.0926

So we can see that Brand A has a lower unit price, meaning that is a better option.
