Question

a. A school receives 2000 e-mail messages each day. Of those messages, 1250 are junk mail messages. Model the number of e-mail messages received by the school that are not junk mail.

Answer 1

the school receives 750 emails that are not junk

Answer 2

Okay so to model the number of messages first you'd take the values and make an equation, so the school receives 2000 email messages and out of those messages 1250 are junk mail so 2000=1250+x , x represents the number of emails that are not junk mail so we subtract 1250 from 2000 to get 750 so 2000=1250+750 is the equation.
