Question 10 • Mathematics 8

Esther made the given two-way table showing the number of her schoolmates who have different pets. Students’ Pets Cats Dogs Total 7th Grade 8th Grade 26 35 61 Total 54 48 Which shows the correct values for Esther’s seventh-grade classmates who have pets?

Answer
A
cats: 80; dogs: 83
B
cats: 83; dogs: 80
C
cats: 28; dogs: 13
D
cats: 13; dogs: 28

Explanation

The column totals include both grades. The 8th-grade counts are 26 students with cats and 35 with dogs, so subtract these from the totals: 54 − 26 = 28 cats and 48 − 35 = 13 dogs. Esther’s seventh-grade classmates therefore include 28 students with cats and 13 with dogs, which is choice C.
