A baker’s dozen includes 13 rolls for the price of a dozen rolls. How much money is saved by buying a baker’s dozen instead of 1
KatRina [158]

Answer:

$0.60

Step-by-step explanation:

If you purchase 6 rolls, you pay $3.60

Each roll is $0.60.

If you purchase 13 individual rolls, you pay

13 x 0.6 = $7.80

But if you purchase the Baker's dozen, you pay only $7.20, so you save $0.60

7.80 - 7.20 = 0.60

Hope this helps! :)
