Here let x = inches containing 1120 calories of chocolates

Therefore

\(\frac{3}{7} * \frac{1}{80}= \frac{x}{1120}\)

or \(x = 6\)inches.

Therefore number of helpings for 6 inches = \(\frac{7}{3} * 6\)= 14 helping

Isn't the information about inches superfluous? I mean we know an helping is 3/7 long and it has 80 calories but the length has nothing to do with calories. Then, since Bubba has consumed 1120 calories, it has consumed \(\frac{1120}{80} = 14\) helpings
