What is the equation for a banana has 90 calories and it is 5ess calories than one seventh of the calories in a banana split how many calories are in a banana split

Answer: 665

Solution:

total number of calories in a banana = 90 calories

Let the number of calories in a banana split = x

one seventh of the calories in a banana = 1/7 x

The equation:

(1/7) x - 5 = 90

(1/7) x - 35 = 90 (Take LCM)

x - 35 = 90 * 7

x - 35 = 630

x = 630 + 35

x = 665
