Graph \( f(x)=3 x^{2}+24 x+49 \)

7. Mrs. Ocosta is paid a \( 5 \% \) commission on her sales each week. In addition, she receives a base salary of \( \$ 375 \). What should the amount of her sales be for the week if she hopes to make at least \( \$ 600 \) this week?

5. \( 2 x-17 \geq 29 \)

3 girls and 4 boys share \( \$ 170 \). Each girl receives twice as much money as each boy. How much money does each girl receive?

solve the insquality \( n+7<5 n-8 \).

Vhich expression means the product of 125 and a number \( \begin{array}{llll}\text { (b) } 125+x & \text { (c) } 125-x & \text { (d) } 125 \div x\end{array} \)
