Answers:

1- B
\(36 ÷ 3 = 12\) hours for one course
\(12 × 25 = 300 ⇒ $300\)

2- D
Plug in the value of \(x\) and \(y\).
\(x=3\) and \(y=-2\)
\((5(x-2y)+(2-x))^2=(5(3-2(-2))+(2-3))^2=(5(3+4)+(-1))^2 = (34)^2=36\)

3- D
Michelle = Karen – 9
Michelle = David – 4
Karen + Michelle + David = 82
Karen + 9 = Michelle ⇒ Karen = Michelle – 9
Karen + Michelle + David = 82
Now, replace the ages of Karen and David by Michelle. Then:
Michelle + 9 + Michelle + Michelle + 4 = 82
3Michelle + 13 = 82 ⇒ 3Michelle = 82 – 13
3Michelle = 69
Michelle = 23

4- D
The equation of a line in slope intercept form is: \(y=mx+b\)
Solve for \(y\).
\(4x-2y=12 {\Rightarrow} -2y=12-4x {\Rightarrow} y=(12-4x){\div}(-2) {\Rightarrow} y=2x-6\)
The slope of this line is 2.
The product of the slopes of two perpendicular lines is \(-1\).
Therefore, the slope of a line that is perpendicular to this line is:
\(m_{1} {\times} m_{2} = -1 {\Rightarrow} 2 {\times} m_{2} = -1 {\Rightarrow} m_{2} = \frac{-1}{2}\)

5- B
Since Julie gives 8 pieces of candy to each of her friends, then, then number of pieces of candies must be divisible by 8.
A. \(187 ÷ 8 = 23.375\)
B. \( 216 ÷ 8 = 27\)
C. \( 343 ÷ 8 = 42.875\)
D. \(223 ÷ 8 = 27.875\)
Only choice B gives a whole number.

6- D
Use FOIL method.
\((2x+2y)(2x-y) = 4x^2-2xy+4xy-2y^2=4x^2+2xy-2y^2\)

7- A
The base rate is $15.
The fee for the first 40 visits is: \(40×0.20=8\)
The fee for the visits 41 to 60 is: \(20×0.10=2\)
Total charge: \(15 + 8 + 2 = 25\)

8- D
To solve absolute values equations, write two equations.
\(x-10\) could be positive 3, or negative 3. Therefore,
\(x-10=3 \Rightarrow x=13\)
\(x-10=-3 \Rightarrow x=7\)
Find the product of solutions: \(7 \times 13 = 91 \)

9- D
Solving Systems of Equations by Elimination
Multiply the first equation by \((-2)\), then add it to the second equation.
\({-2(2x+5y= 11) \ 4x-2y=-14} {\Rightarrow} {-4x-10y= -22 \ 4x-2y=-14} {\Rightarrow} {-12y= -36} {\Rightarrow} {y= 3}\)
Plug in the value of y into one of the equations and solve for \(x\).
\(2x+5(3)= 11 {\Rightarrow} 2x+15= 11 {\Rightarrow} 2x= -4 {\Rightarrow} x= -2\)

10- D
Change 9 hours to minutes, then: \(9 × 60 = 540\) minutes
\(\frac{540}{90}=6\)
