Final answer:

The correct answer to what percent of last semester's college cost was spent on books is 12%, calculated by dividing $264 by $2,200 and then multiplying by 100. Percentages have no dimension. Hence it is called a dimensionless number. If we say, 50% of a number, then it means 50 per cent of its whole.

Step-by-step explanation:

The student wants to know what percentage of last semester's college cost was spent on books. We have the total college cost of last semester, which was $2,200, and the amount spent on books, which was $264. To find the percentage, we use the formula for percentage:

Percentage = (Part / Whole) × 100

Thus, the percentage spent on books is calculated as:

Percentage = ($264 / $2,200) × 100

This calculation yields Percentage = 12%. Therefore, the correct answer is a) 12%.

a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Percentages can also be represented in decimal or fraction form, such as 0.6%, 0.25%, etc. In academics, the marks obtained in any subject are calculated in terms of percentage. Like, Ram has got 78% of marks in his final exam. So, this percentage is calculated on account of the total marks obtained by Ram, in all subjects to the total marks.
