I'm assuming you want to know what 45% of 360 is.....
so you multiply 360 by 0.45 (since 45 is a percent, and to revert it back, you must move the decimal 2 times to the left) and you have your answer...
Because if let's say you have 400$ for the year, and each book cost 10$. So it would be written as 400-10b since the quantity of books must be multiplied times their cost to calculate whether you are within or outside the budget.
How many students had 3 or more absences? Add together {45%, 21%, 23%} and subtract that sum from 100%: 11%.
How many students had two or more absences? Add together this 11% and 21%: 32% had two or more absences. Let the total number of students be n. Then 32% of these n students add up to 96 students. Thus, 0.32n = 96, and n= 300.
How many students had one absence? The chart shows that that is 45%, and we know that there are 300 students total.
Thus, the number of students who had one absence was 0.45(300) = 135.
Find the factors from the roots, then multiply the factors together.
