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?
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
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.
