Answer:
The 5 cans for $1.55 is a better bargain because the unit price for these cans is $0.31, while the unit price for the other is $0.33
Explanation:
Unit price tells you the cost per liter, per kilogram, per pound, etc, of what you want to buy. So for this problem you want to figure out how much each can is worth and which is the better deal.
You would do $1.55 ÷ 5 = 0.31 cents per can
The other equation would be $0.99 ÷ 3 = 0.33 cents per can
So the better bargain is the 5 cans for $1.55
