Question

A group of middle school students completed a survey about ice cream flavors. They were asked two questions, “Do you like Fudge Swirl Ice Cream?” and “Do you like Pistachio Ice Cream?” When the results were tallied, 87 answered yes to Fudge Swirl, 72 answered yes to pistachio, 58 responded yes to both, and 14 said no to both flavors. How many students were surveyed?

Answer 1

87+72= 159+14= 173 students were surveyed.

Answer 2

yes to Fudge: 87 - 58 = 29
yes to Pistachio: 72 - 58 = 14

yes to both = 58
no to both = 14

total asked: 58 + 14 + 29 +14 = 115 people
