Charlie's horse, Star, was getting too heavy eating 3 1/2 pounds of horse feed twice a day. Charlie reduced Star's feed by 3/4 of a pound at each feeding. How much is Star now eating each day?
Star was initially eating 3 1/2 pounds * 2 = <<3.5*2=7>>7 pounds of feed each day.
Charlie reduced each feeding by 3/4 pounds, so each feeding is now 3 1/2 - 3/4 = 2.75 pounds,
So, Star is now eating 2.75 pounds * 2 = <<2.75*2=5.5>>5.5 pounds each day. Answer: \boxed{5.5}.
To determine how much Star is eating each day after Charlie reduced the feed, we will need to calculate the original amount of feed and then subtract the reduced amount.
The original amount of feed Star was eating each day was 3 1/2 pounds twice a day, which can be written as:
3 1/2 pounds/day * 2 = 7 pounds/day
Next, we need to find out the reduced amount of feed by subtracting 3/4 of a pound at each feeding:
7 pounds/day - 3/4 pound - 3/4 pound
= 7 - (3/4) - (3/4)
= 6 1/2 pounds/day
Therefore, Star is now eating 6 1/2 pounds of feed each day.
To find out how much Star is now eating each day, we need to subtract the reduced amount from the original amount.
First, let's calculate the original amount Star was eating each day:
Star was eating 3 1/2 pounds of horse feed twice a day, so:
3 1/2 pounds * 2 = 7 pounds
Now, let's calculate how much Star's feed was reduced by:
Star's feed was reduced by 3/4 of a pound at each feeding, so:
3/4 pound * 2 = 1 1/2 pounds
Finally, subtract the reduced amount from the original amount to find out how much Star is now eating each day:
7 pounds - 1 1/2 pounds = 5 1/2 pounds
Therefore, Star is now eating 5 1/2 pounds of horse feed each day.
