Over the last three evenings, Kira received a total of 86 phone calls at the call center. The first evening she received 1p fewer call than the second evening. The third evening, she received 2 times as many calls as the first evening. How many phone calls did she receive each evening?
evening 1: x-1
evening 2: x
evening 3: 2(x-1)
x-1 + x + 2(x-1) = 86
solve for x and then finish up.
I suspect a typo. what is "1p" ?
