Final answer:
To solve the inequality 5c ≤ 1, divide both sides by 5 to isolate c. The solution in set-builder notation is c .
Step-by-step explanation:
To solve the inequality 5c ≤ 1, we need to divide both sides of the inequality by 5 to isolate c. Divide 1 by 5 to get 1/5. So the inequality becomes: c ≤ 1/5.
The solution in set-builder notation is c ≤ 1/5. This represents the set of all values of c that are less than or equal to 1/5.
