Nicholas sold pounds of shrimp in 4 hours. So, he sells shrimp at a rate of
pounds of shrimp per hour. At this rate, he would sell
pounds of shrimp in 9 hours.
We don't have the value of the amount of shrimp Nicholas sold, so let's call it "x" pounds.
We know that he sold x pounds in 4 hours, so his rate of selling shrimp is:
x pounds / 4 hours = x/4 pounds per hour
To find out how many pounds of shrimp he would sell in 9 hours at this rate, we can use the formula:
amount of shrimp = rate x time
So,
amount of shrimp = (x/4) pounds per hour x 9 hours
amount of shrimp = (9x/4) pounds
Therefore, at this rate, Nicholas would sell 9x/4 pounds of shrimp in 9 hours.
