Hi Bunuel,
I don't understand the wording of the last sentence of the question.
I don't understand why we have divided 48/64 in order to calculate percentage. 48% is nothing but 48% of salary spent on food and not on meat.
Can you explain so I can understand why you have divided 48/64

Official Solution:
Mary spent 64 percent of her salary on food (including meat) and 16 percent of her salary on meat. What percent of her salary spent on food was not spent on meat?
A. \(16%\)
B. \(25%\)
C. \(32%\)
D. \(48%\)
E. \(75%\)
Mary spent:
64% of her salary on food (including meat);
16% of her salary on meat;
Therefore, 64% - 16% = 48% of her salary was spent on food excluding meat. Thus, \(\frac{48}{64} = \frac{3}{4} = 75\%\) of the salary spent on food was not spent on meat.
Answer: E
The question asks: what percent of the
food budget was not spent on meat, not what percent of the
salary.
Mary spent 64% of her salary on food, and 16% on meat. So 48% of her salary was spent on food
excluding meat.
To find what portion of the
food budget that is, we divide:
48/64 = 75%
So, 75% of the
food spending was not on meat. That's why 48 is divided by 64.
