Mae sold raffle tickets to Steven and to Theo. Each ticket costs k dollars. Steven bought \( 10 \) raffle tickets. Theo bought \( 15 \) raffle tickets. Which expression must be equal to the difference between how many dollars Theo spent and how many dollars Steven spent? A. \( 5 + k \) B. \( 5 - k \) C. \( 5 \) K D. \( 5 / k\) 

2) \( 3 x+\frac{9}{7}=\frac{5 x}{3}+11 \)

\( 2 ^ { x } \cdot \log _ { 3 } x + 3 ^ { x } \cdot \log _ { 2 } x \leq 2 \cdot 3 ^ { x - 1 } \cdot \log _ { 3 } x + 3 \cdot 2 ^ { x - 1 } \cdot \log _ { 2 } x \)

7. \( 2 x^{2}+3 x-3=0 \) tanliyini hall edin. A) \( \frac{-3 \pm \sqrt{33}}{4} \) B) \( \frac{3 \pm \sqrt{15}}{4} \) C) \( \frac{-3 \pm \sqrt{27}}{4} \) D) \( \frac{3 \pm \sqrt{27}}{5} \)

2) For the linear function \( f \) if \( f(2)=2 \) and \( f(4)=5 \). chen for whal value of \( x \) is \( f(x)=0 \) ? \( \begin{array}{lllll}\text { (A) } \frac{2}{3} & \text { (B) } \frac{3}{4} & \text { (C) } 1 & \text { (D) } \frac{4}{3} & \text { (E) } \frac{3}{2}\end{array} \)

Sonny is twice as old as Wale. Four years ago, he was four times as old as Wale. When will the sum of their ages be 66 ?
