Final answer:
The equation that relates the number of gifts that Keisha and Abdul wrapped is 18 = 9n
Step-by-step explanation:
To write an equation that relates the number of gifts that Keisha and Abdul wrapped, we need to first determine the relationship between the two.
It is stated that Keisha wrapped 9 times as many gifts as Abdul.
Let n be the number of gifts Abdul wrapped.
Keisha wrapped 18 gifts, so we can write the equation as:
Keisha's gifts = Abdul's gifts x 9
18 = n x 9
Therefore, the correct equation that relates the number of gifts that Keisha and Abdul wrapped is 18 = 9n, which is option D.
