Answer:
12 tins of fish at K7.80
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.
