Complete question is;
Keisha needs to make at least 32 costumes for the school play. Since she can make 4 costumes each week, Keisha plans to work on the costumes for at least 8 weeks.
Which inequality matches the problem?
A) x ≥ 8
B) x = 8
C) x ≤ 8
D) none of the above
Answer:
A: x ≥ 8
Step-by-step explanation:
Let the number of weeks be x.
She needs to make at least 32 costumes and plans to work at least 8 weeks. Since she makes 4 costumes per week, we can say that;
4x ≥ 32
I used greater than or equal to sign because she can't make less than 32 costumes.
Also, she can't use less than 8 weeks.
Thus; dividing both sides by 4, we have;
4x/4 ≥ 32/4
x ≥ 8
