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.
is this 4 separate problems? If so, do them all the same way: just add up the quantities:
(a) 250+150 = 400
To find out how many bags of rice have been shipped in or shipped out within two days, we need to calculate the net difference between the number of bags shipped in and the number of bags shipped out for each day.
a) For day one, we have 250 bags shipped in, and for day two, we have 150 bags shipped out. To calculate the net difference for each day, we subtract the number of bags shipped out from the number of bags shipped in:
Day one: 250 bags shipped in - 0 bags shipped out = 250 bags net difference
Day two: 0 bags shipped in - 150 bags shipped out = -150 bags net difference
The net difference for the two days combined is calculated by adding the net differences for each day:
250 bags net difference + (-150) bags net difference = 100 bags net difference
b) For day one, we have 0 bags shipped in, and for day two, we have 120 bags shipped out.
Day one: 0 bags shipped in - 100 bags shipped out = -100 bags net difference
Day two: 0 bags shipped in - 120 bags shipped out = -120 bags net difference
The net difference for the two days combined is calculated by adding the net differences for each day:
(-100) bags net difference + (-120) bags net difference = -220 bags net difference
c) For day one, we have 0 bags shipped in, and for day two, we have 140 bags shipped in.
Day one: 0 bags shipped in - 180 bags shipped out = -180 bags net difference
Day two: 140 bags shipped in - 0 bags shipped out = 140 bags net difference
The net difference for the two days combined is calculated by adding the net differences for each day:
(-180) bags net difference + 140 bags net difference = -40 bags net difference
d) For day one, we have 175 bags shipped in, and for day two, we have 0 bags shipped out.
Day one: 175 bags shipped in - 0 bags shipped out = 175 bags net difference
Day two: 175 bags shipped in - 0 bags shipped out = 175 bags net difference
The net difference for the two days combined is calculated by adding the net differences for each day:
175 bags net difference + 175 bags net difference = 350 bags net difference
Therefore, the net difference for each scenario is as follows:
a) 100 bags net difference
b) -220 bags net difference
c) -40 bags net difference
d) 350 bags net difference
