The expression that would represent the total number of students at the summer camp for all three years is (b) 5.5s - 54
<h3>How to determine the expression?</h3>
Let the number of students in 2010 be s.
So, we have:
- Year 2011 = 1/2s i.e. half as many students in 2010
- Year 2012 = s - 54 i.e. 54 students less than 2010
The total number of students is:
Total = s + 1/2s + s - 54
Evaluate
Total = 9s/2 - 54
Rewrite s:
Total = 5.5s - 54
Hence, the expression that would represent the total number of students at the summer camp for all three years is (b) 5.5s - 54

The total cost of the meal is $30.02
Step-by-step explanation:
Given,
Cost of meal = $24.62
Tax = 6%
Tax amount = 6% of cost of meal
Cost after sales tax = 24.62+1.48 = $26.10
Tip = 15%
Tip amount = 15% of cost after sales tax
Total cost of meal = Cost after sales tax + Tip amount
Total cost of meal = 26.10+3.92 = $30.02
The total cost of the meal is $30.02

Answer:
Option C.
Step-by-step explanation:
Equation of the parent function graphed in the figure is,
G(x) = x²
By reflecting the parent function over the x-axis,
G'(x) = -x²
By shifting G'(x) by 2 units down over the y-axis,
f(x) = -x² - 2
Therefore, transformed form of the parent function will be
f(x) = -x² - 2
Therefore, Option C will be the answer.
