2127 chairs

Step-by-step explanation:

Given : Carrie manages a catering company. She rented 325 chairs each week for the first two weeks of May.

Then by using Multiplication operation , the total number of chairs ordered in first two weeks of May. =   (1)

Also,  Carrie rented 750 chairs each week for the first two weeks of April.

Then, the total number of chairs ordered in first two weeks of April =  (2)

Total chairs ordered in 4 weeks = 650+1500     [add (1) and (2)]

 =2150

The chair rental company forgot to send 23 chairs, then number of chairs received by Carrie = 2150-23 =2127

Hence, Carrie received 2127 chairs in those 4 weeks.
