Plz i don't understand i am very 16

5 bars for $4.00 is the better deal

Explanation:

The first ratio is

12 bars : 10 dollars

Divide each part of that ratio by 12 so that "12 bars" turns into "1 bar"

12 bars: 10 dollars

(12/12) bars: 10/12 dollars

1 bar: 0.83 dollars

1 bar: 83 cents

Repeat for the other ratio as shown below. This time we divide both parts by 5 to turn the "5 bars" into "1 bar"

5 bars : 4 dollars

(5/5) bars : 4/5 dollars

1 bar : 0.80 dollars

1 bar : 80 cents

Deal #1 costs 83 cents per bar. Deal #2 is 80 cents per bar. So deal #2 is cheaper by 3 cents.

The better deal is "5 bars for 4 dollars"
