Question

A banana has 80 calories. This is 5 calories less than one seventh of the calories in a banana split. How many calories in a banana split?

Answer 1

Total calories = 80
calories in a banana split = 1/7 of total calories - 5 calories
                                         = $\frac{1}{7} *80-5$
                                   
                                         = $\frac{80}{7} -5$
 
                                         = $\frac{80-35}{7}$
         
                                         = $\frac{45}{7}$
  
                                         = 6.43.......................... rounded to the nearest hundredth

So, there is 6.43 calories in a banana split.

Answer 2

The answer is 85 times 7. Since the banana was 5 less then the split, the split is 5 more which is 85 calories but then it says it is also 1/7 of the whole split. So you simply multiply 85 and 7 because 85 was only 1/7 of the total banana split
