The tins of cat food that I buy are normally 80 cents each. They are also available in packs of 6, but there is no advantage to this as they cost $4.80 My neighbor told me this morning that the everlo supermarket has a special offer this week: 25% off all tins and a further 60 cents off a pack of 6. I have given my son $20 and sent him to Everlo to but as many tins as he can.

39 tins of cat food.

Step-by-step explanation:

I am assuming the question is how the number of tins that can be bought.

Step 1 - Discounted price

With the discount a tin would cost;

= 80 * ( 1 - 25%)

= 60 cents

Step 2 - Packs of 6 purchased at discounted price

Every pack of 6 attracts 60 cents off which means that they are paying the price of 5 tins for 6 tins.

Price of 5 tins;

= 60 * 5

= $3

Out of $20, the number of packs of 6 he can buy are;

= 20/ 3

= 6.67

= 6 packs of 6

Step 3 - Number tins not in pack of 6 bought

If he buys 6 packs of 6 the amount of money left is;

= 20 - ( 6 * 3)

= $2

With these $2, he could buy;

= 200 cents/60 cents

= 3.333

= 3 tins

Step 4 - Total number of Tins bought

The total number of tins he can buy are therefore;

= 6 packs of 6 + 3 tins

= (6 * 6) + 3

= 39 tins of cat food.
