Explanation:

Step1: Calculate the percentage for each option

• Option 1:
• Total customers \(n = 25\), customers who preferred cookie - dough \(x = 21\)
• Percentage \(p=\frac{21}{25}\times100\%=\frac{21\times4}{25\times4}\times100\% = 84\%\)
• Option 2:
• Total customers \(n = 80\), customers who preferred cookie - dough \(x = 63\)
• Percentage \(p=\frac{63}{80}\times100\%= 78.75\%\)
• Option 3:
• Total customers \(n = 16\), customers who preferred cookie - dough \(x = 13\)
• Percentage \(p=\frac{13}{16}\times100\%=\frac{13\times6.25}{16\times6.25}\times100\% = 81.25\%\)
• Option 4:
• Total customers \(n = 30\), customers who preferred cookie - dough \(x = 24\)
• Percentage \(p=\frac{24}{30}\times100\%=\frac{24\div6}{30\div6}\times100\%=\frac{4}{5}\times100\% = 80\%\)

Answer:

Leo surveyed 30 customers, and 24 preferred cookie dough ice cream.
