12 tins of fish at K7.80

Step-by-step explanation:

The first quote is the best buy.

If we evaluate both quotes we would see that.

For the first one, we have:

12 tins of fish at K7.80

Therefore the cost of one tin would be; K7.80/12= K0.65

For the second;

6 tins of fish at K4.20, one tin cost

K4.20/6=K0.70

So we see we are paying less for the cost of one tin of fish in the first quote.
