The number of fat grams in a Whopper exceeds the fat grams in a Big Mac by eleven. If you add the fat grams in a Whopper and a Sonic Cheeseburger, it is seven less than three times the fat grams in a Big Mac. Twice the amount of the fat grams in all three is 222. Find the fat content of each burger using the matrix method. </SPAN>\n" );
