Answer

Explanation:

Step1: Calculate total students surveyed initially

$10 + 7+4 + 5=26$

Step2: Find the proportion of students who prefer water - cooler

The proportion of students who ranked water - cooler as first choice is $\frac{7}{26}$.

Step3: Estimate number for next 50 students

Multiply the proportion by 50: $\frac{7}{26}\times50=\frac{350}{26}\approx13.46$
