How many peppers did Peter picked?

[Chris_Stevens]

Peter picked 60 peppers as the second last statement could read.
OR
After a whole bunch of math:
I got Peter picked 67/4 lol! did something wrong...

[Chris_Stevens]

I re-did the math and it works!

A=Peter B=Paul C=Pam D=Pat

Statements:
A=B+1
D=C+1
A+B=C+D+10
A+B+C+D=60

A= ?

B = A - 1
D = C +1

A + (A - 1) = C + (C + 1) + 10
2A - 1 = 2C +11
2A = 2C + 12
A = C + 6

C = ?

A = C + 6
D = C + 1
B = C + D + 10 - A
B = C + C+1 + 10 - (C + 6)
B = 2C + 11 - C - 6
B = C + 5

C = 60 - (C+6) - (c+5) - (C+1)
C = 60 - 6 -c -C - 5 - C - 1
C = 48 - 3C
4C = 48
C = 12

A = 12 + 6 = 18

Peter = 18 picked
