13) An airline weighed the carry-on luggage of all its 1,106 passengers in a single day. How many of these passengers had carry-on luggage that weighed less than 20 lb? *

Respuesta :

we know that

4 lb or less ------> is less than 20 lb ------> 120

5-9 lb------------> is less than 20 lb -------> 222

10-14 lb -------> is less than 20 lb ------->378

15-19 lb ------> is less than 20 lb-------> 256

Adds the number of passenger

120+222+378+256=976

therefore

the answer is 976
