Answer 1

Inequality: 20x ≤ 240 (where x represents the number of toys)

Solve:
20x ≤ 240
Divide both sides by 20:
x ≤ 12

Solution: Ms. Johnson can make at most 12 doggie toys each day.

Explanation: The solution of x ≤ 12 means that she can make 12 or fewer toys in order to stay within her time constraint of 240 minutes.
