Question 1108606
Over the last three evenings, Latoya received a total of 
145 phone calls at the call center. The third evening, she received 
4 times as many calls as the second evening. The first evening, she received 
5fewer calls than the second evening. How many phone calls did she receive each evening? 
-----
F + S + T = 145 calls
T = 4S
F = S-5
------------------------
Substitute for T and for F ; Solve for "S"::
S-5 + S + 4S = 145
6S = 150
S = 26 (# on 2nd evening)
T = 4S = 104 (# on 3rd evening)
F = S-5 = 21 (# of 1st evening)
