Find out how many bags of rice have been shipped in or shipped out within two days:

a) Day one, 250 bags have been shipped in; Day two, 150 bags have been shipped out.

b)Day one, 100 bags have been shipped out; Day two, 120 bags have been shipped out.

c)Day one, 180 bags have been shipped out; Day two, 140 bags have been shipped in.

d)Day one, 175 bags have been shipped in; Day two, 175 bags have been shipped in.

a) To find out how many bags of rice have been shipped in or shipped out within two days, we need to calculate the net quantity by subtracting the bags shipped out from the bags shipped in.

Day one: 250 bags shipped in
Day two: 150 bags shipped out

Net quantity = Bags shipped in - Bags shipped out
= 250 - 150
= 100 bags

Therefore, 100 bags of rice have been shipped in or shipped out within two days.

b) Day one: 100 bags shipped out
Day two: 120 bags shipped out

Net quantity = Bags shipped in - Bags shipped out
= 0 - (100 + 120)
= 0 - 220
= -220 bags

Therefore, a negative value means that no bags were shipped in or shipped out within two days.

c) Day one: 180 bags shipped out
Day two: 140 bags shipped in

Net quantity = Bags shipped in - Bags shipped out
= 140 - 180
= -40 bags

Therefore, a negative value means that no bags were shipped in or shipped out within two days.

d) Day one: 175 bags shipped in
Day two: 175 bags shipped in

Net quantity = Bags shipped in - Bags shipped out
= (175 + 175) - 0
= 350 bags

Therefore, 350 bags of rice have been shipped in or shipped out within two days.

To find out how many bags of rice have been shipped in or shipped out within two days for each scenario, you will need to add the numbers of bags that were shipped in and subtract the numbers of bags that were shipped out.

a) For scenario a, on day one, 250 bags were shipped in, and on day two, 150 bags were shipped out. To find the total, subtract the bags shipped out from the bags shipped in: 250 - 150 = 100 bags. Therefore, there were 100 bags shipped in or out within two days.

b) For scenario b, on day one, 100 bags were shipped out, and on day two, 120 bags were shipped out. To find the total, subtract the bags shipped out from the bags shipped in: 0 - (100 + 120) = -220 bags (negative value means more bags were shipped out than shipped in). Therefore, there were -220 bags shipped in or out within two days.

c) For scenario c, on day one, 180 bags were shipped out, and on day two, 140 bags were shipped in. To find the total, subtract the bags shipped out from the bags shipped in: 140 - 180 = -40 bags (negative value means more bags were shipped out than shipped in). Therefore, there were -40 bags shipped in or out within two days.

d) For scenario d, on day one, 175 bags were shipped in, and on day two, 175 bags were shipped in. To find the total, subtract the bags shipped out from the bags shipped in: (175 + 175) - 0 = 350 bags. Therefore, there were 350 bags shipped in or out within two days.

In summary:
a) 100 bags shipped in or out within two days.
b) -220 bags shipped in or out within two days.
c) -40 bags shipped in or out within two days.
d) 350 bags shipped in or out within two days.
