In order to get the answer to this problem, first we have to find out how many pounds does one case of pancake mix have. We know that one box has 1.3 pounds of pancake mix. We also know that one case has 12 boxes. So first, we multiply 1.3 to 12.  The answer we will get is 15.6. One case of pancake mix has a total of 15.6 pounds of pancake mix. Now we also know there are 7.5 cases that George bought. So in order to get the total pounds George bought, we multiply 15.6 to 7.5. So all in all, George bought 117 pounds of Pancake Mix. 

Answer:

117 pounds of pancake mix was bought by George.

Step-by-step explanation:

We are given the following in the question:

Total number of cases of pancake bought =  7

Number of boxes in a case = 12

Total Number of boxes =

[tex]\text{Number of cases}\times \text{Number of box in a case} = 7.5\times 12\\= 90[/tex]

Weight of one box = 1.3 pounds

Total pounds of pancake mix bought =

[tex]\text{Total number of boxes}\times \text{Weight of 1 box} = 90\times 1.3\\= 117[/tex]

Thus, 117 pounds of pancake mix was bought by George.
