A bag of potatoes and a bag of oranges weigh 30 pounds in all. The weight of the potatoes is 5 pounds less than 4 times the weight of the oranges. Let w represent the weight of the oranges. The equation that can be used to find the value of w is (4 w minus 5) + w = 30. Which shows the first step that should be taken to verify that w, the weight of the bag of oranges, equals 7? A. (4 (7) + 5) + 7 = 30
B. (4 (7) minus 7) + 5 = 30
C. (4 (7) + 5) minus 7 = 30
D. (4 (7) minus 5) + 7 = 30
