Question

Over the last three evenings, Teresa received a total of 102

phone calls at the call center. The third evening, she received 3

times as many calls as the first evening. The second evening, she received 8

fewer calls than the first evening. How many phone calls did she receive each evening?

Answer 1

x=# of calls the first evening

x-8=# of calls the second evening

3x=# of calls the third evening

 

x+(x-8)+3x=102

5x-8=102

5x=102+8

5x=110

x=110/5

x=22 calls the first evening

x-8=14 calls the second evening

3x=66 calls the third evening
