Question

There are 32 people on the bus in the morning and 40 people on the bus in the afternoon. Of 20 people only ride the bus in the afternoon, how many people only ride the bus in the morning?

Answer 1

Hi, Maralmaa.

 

Okay, so if 40 people ride the bus in the afternoon, but only 20 of them only ride the bus in the afternoon, then 20 of them ride the bus in the morning and the afternoon. Therefore, of the 32 people who ride the bus in the morning, 20 of them ride both in the morning and the afternoon, so 32 - 20 = 12 people only ride the bus in the morning.

 

Therefore, 12 people only ride the bus in the morning.
