3 kilograms of charcoal for $7.95 or 5 kilograms of charcoal for $12.50

5 kilograms of charcoal for $12.50

Step-by-step explanation:

first find price of 1kg:

3 kilograms of charcoal for $7.95 = 7.95/3 = $2.65 ($2.65 for each kg)

so when you get 5 kgs for $2.65 each, it would be total $13.25 (5*$2.65)

and that is more than the price of other one

5 kilograms of charcoal for $12.50 = 12.50/5 = $2.5 ($2.5 for each kg)
