Steps/Work
M = 3P
L = P+5
M + P + L = 30
3P + P + (P+5) = 30
P = 5, M = 15, L = 10
Therefore, Mary, Peter, and Lucy picked 15, 5, and 10 kg, respectively.
The answer is C.
L = P+5
M + P + L = 30
3P + P + (P+5) = 30
P = 5, M = 15, L = 10
Therefore, Mary, Peter, and Lucy picked 15, 5, and 10 kg, respectively.
The answer is C.
