The graph shows the average numbers of different fish that are found in the Red Sea. Which two fish have the same number?

In order to answer this question, we need to look at the heights on the 𝑦-axis of all the different types of fish. The two types of fish that have the same number will be of the same height. There are two types of fish that are equal to 40. Reading down to the 𝑥-axis from these two points shows that they are marlin and mullet. We can therefore say that marlin and mullet have the same number of fish in the Red Sea.
