I would like to explain and solve the math word problem.

~~~~~~~~~~~~~~

Let x be the amount John paid for the food.

Then the additional amount of 10%, which John paid, is 0.1x.


The total John paid was x + 0.1x = 1.1x.


We are given that the total is $44.


It gives us this equation

    1.1x = 44  dollars.


Divide both sides by 1.1 and get x

    x =  = 40.


Thus John paid for food $40.


The additional amount John paid was 0.1*40 = 4 dollars.

Solved in full, with complete explanations.
