Answer

14 more people bought Blue Bell ice cream than Benn & Jerry ice cream.

Work Step by Step

We see from the table that $5.4\%$ preferred Blue Bell ice cream and $4.5\%$ preferred Ben and Jerry ice cream. Thus the difference is: $5.4-4.5=0.9\%$ We find what number of people this comes out to by multiplying by the total amount of people surveyed (1582): $0.009*1582\approx14.2\approx 14$ people Thus 14 more people bought Blue Bell ice cream than Benn & Jerry ice cream.
