Answer:
50 songs
Step-by-step explanation:
To know how many songs he downloaded of each type, we just need to see where each bar stops and see the number that is just below.
Carl downloaded 15 songs of country music, 20 of rock, 5 of classical and 10 of world.
If we want to know the total of songs, we just need to sum them all:
15 + 20 + 5 + 10 = 50
He downloaded 50 songs last year.
