Answer 1

Hi Ellie,

Step One: Find the cost of buying bagels singly:

Cost for buying bagels singly=(Cost of one bagel)(Number of individual bagels)

Cost for buying bagels singly=(1.50)(104)

Cost for buying bagels singly=156

Step Two: Find the cost of buying bagels in a baker's dozen package

Since we have 104 bagels total and a baker's dozen in 13 bagels, we calculate 104/13=8 in order to find how many baker's dozen orders that he must pay for. 

Now, since we found that we have 8 sets of 13:

(Cost per bakers set)(Number of sets)=Cost of buying in a bakers dozen

(9)(8)=Cost of buying in a bakers dozen

72=Cost of buying in a bakers dozen

Step Three: Compare the two cost values

Buying Singly costs $156 while buying in a baker's dozen package costs $72. To find how much she would save:

156-72=The Amount Saved

$84=The Amount Saved
