Question 1118659
Let's start with the equality:
Meal A has 1 gram more than 3 times B. Write it like it reads:
A = 3B + 1 We'll use this value for A below.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A-B = 19
3B+1-B = 19
2B = 18
B = 9
and A = 3B +1 = 3(9)+1 = 27+1 = 28
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Check: The difference in fat content between A and B is 19 grams:
28 - 9 = 19 Correct
