Oliver completed his project in no more than twice the amount of time it took Karissa to complete her project. Oliver spent 4 and 1 fourth hours on his project. If k represents the amount of time that it took Karissa to complete her project, which inequality can be used to represent the situation?
Answer
A
4 and 1 fourth is greater than or equal to 2 k
B
4 and 1 fourth is less than 2 k
C
4 and 1 fourth is less than or equal to 2 k
D
4 and 1 fourth is greater than 2 k
Explanation
“No more than twice” means Oliver’s time is less than or equal to twice Karissa’s time. Oliver spent 4 and 1 fourth hours, and twice Karissa’s time is 2k, so the inequality is 4 and 1 fourth ≤ 2k. This matches choice C, “4 and 1 fourth is less than or equal to 2k.”
