Answer: 20

Step-by-step explanation:

Given : The orchestra at millard middle school has 120 members.

Of these 17% are eighth grade students.

i.e. Percentage of eighth grade students in orchestra = 17%

Then, the number of eighth grade students in the orchestra. = (Percentage of eighth grade students in orchestra) x ( Total members in orchestra)

= 17% x 120

[tex]=\dfrac{17}{100}\times120[/tex] [We convert % into decimal by dividing it by 100]

[tex]=20.4\approx20[/tex] [Round to the nearest integer.]

Hence, the estimated number of eighth grade students in the orchestra is 20.
