Working with the given percentages, we will get:
- 125% of last year's attendance = 270
- 25% of last year's attendance = 54
- 100% of last year's attendance = 216
<h3>
How to find the missing values?</h3>
Here we need to work with percentages.
Let's say that X is last year's attendance. We know that 270 is the 125% of last year's attendance, then we will have the relation:
X*(125%/100%) = 270
X*1.25 = 270
X = 270/1.25 = 216
This means that last year's attendance was of 216 people.
The 25% of that is:
216*(25%/100%) = 216*(0.25) = 54
then we can complete the 3 blanks as:
125% of last year's attendance = 270
25% of last year's attendance = 54
100% of last year's attendance = 216

We have,
The expanded form of given sum is:
Therefore, the correct option is C.
Answer:
(x - 3) • (x^2 - 4x - 7)
Step-by-step explanation:
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-4x-7
The first term is, x2 its coefficient is 1 .
The middle term is, -4x its coefficient is -4 .
The last term, "the constant", is -7
Step-1 : Multiply the coefficient of the first term by the constant 1 • -7 = -7
Step-2 : Find two factors of -7 whose sum equals the coefficient of the middle term, which is -4 .
-7 + 1 = -6
-1 + 7 = 6
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
(x - 3) • (x2 - 4x - 7)
