Answer:
18 members voted in favor of the new tax.
Step-by-step explanation:
Given:
Number of members = 20
Percent of members voted in favor of tax = 90 %.
Therefore, as per question,
Number of members voted in favor of tax = [tex]90\% \textrm{ of }20=\frac{90}{100}\times 20=0.90\times 20 = 18[/tex]
Hence, 18 members voted in favor of the new tax.
