Solution
The correct option is A 34
By analyzing the given line graph, we can tabulate the number of African penguins corresponding to each year, as shown below.
Difference in the number of penguins between 2017 and 2019 = Number of penguins in 2019 − Number of penguins in 2017
= 310 − 276
= 34
Thus, there were 34 more African penguins in 2019 than in 2017.
By analyzing the given line graph, we can tabulate the number of African penguins corresponding to each year, as shown below.
Difference in the number of penguins between 2017 and 2019 = Number of penguins in 2019 − Number of penguins in 2017
= 310 − 276
= 34
Thus, there were 34 more African penguins in 2019 than in 2017.
