Data:
Miles needs to make at least $200 (greather than or equal to)
He receives one-eighth of his total sales
Let x be the amount in sell
[tex]\frac{1}{8}x\ge200[/tex]Use the inequality above to find the amount in sell Miles need to do:
[tex]\begin{gathered} \text{Multiply both sides of the inequality by 8:} \\ \\ (8)\cdot\frac{1}{8}x\ge(8)\cdot200 \\ \\ x\ge1600 \end{gathered}[/tex]Then, Miles need to sell at least $1,600 to make at least $200
