Answer:

See the explanation.

Step-by-step explanation:

It is told that, 330 students that are surveyed, are 9th graders.

Hence, 0.55 represents 330 students, that is 1 represents [tex]\frac{330}{0.55}[/tex] = 600 students.

The number of 9th grade students whose favorite elective is music is represented by 0.18.

1 ≡ 600

0.18 ≡[tex]600\times0.18[/tex] = 108.

The percentage of students whose favorite elective is home economics and are also in 10th grade is [tex]\frac{0.06}{1} \times100[/tex] = 6%.
