You plan to cook salmon and divide it among 6 guests. You want each guest to get at least ½ lb. of salmon. How much salmon do you need to buy? Write an inequality, solve it, and graph the solution.
Let x be the amount of salmon in pounds that needs to be bought.
Since each guest should have at least ½ lb of salmon, the total amount of salmon should be at least 6 guests * ½ lb of salmon/guest = 3 lbs of salmon.
Therefore, the inequality representing this situation is:
x ≥ 3
To graph the solution, we represent the inequality on a number line:
[3, +∞)
