C
Explanation: The total time spent practicing over 4 days cannot be less than 10 minutes per day, which is represented by the inequality m ÷ 4 ≥ 10. Additionally, we know that m is greater than or equal to 10 each day, which means m ≥ 10 must be true for all 4 days.
Brian spent a total of m minutes practicing free-throws over 4 days. He spent at least 10 minutes practicing each day. Which inequality could be used to find the possible values of m?
Responses
A m ÷ 4 ≤ 10m ÷ 4 ≤ 10
B 4m ≥ 104 m ≥ 10
C m ÷ 4 ≥ 10m ÷ 4 ≥ 10
D 4m ≤ 10
