Viktor [21]

Answer: State B = 583 mp ; State A = 1,362 mp

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

State A = produced 779 million pounds more apples than State B.

Together the two states produced 1945 million  pounds.

Using "x" as the  pounds of apples produced by State B.

  • State A = 779 + X
  • State B = X

State A + State B = 1945

Replacing with the values of both States

779+X+X =1945

779 +2X =1945

2X = 1945-779

X = 1,166 /2 =583

We have found the amount in State B.

State B = 583

Replacing on A..

State A = 779 + X = 779 + 583 = 1,362
