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 13 individual rolls?

Question

Number of rolls  6           8        Baker’s dozen  

Price ($)         3.60      $4.80           $7.20

Answer 1

Hi Jonaseth

 

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
