Answer:
Step-by-step explanation:Answer: 138 plates are to be washed by her if she started at 7:15 and ends at 7:38, and the function will be f(x)=6x.
Explanation:
Since we have given that
She washed 30 plates from 7:30 to 7:35,
That means in 5 minutes, the number of plates get washed here = 30
We need to find the number of plates from 7:15 to 7:38
First, we count the number of minutes
In 1 minute, the number of plates gets washed by her is given by
In 23 minutes, the number of plates gets washed by her is given by
The equation to represent how many plates Ana has left to wash at a particular time after her start at 7:15 is given by
Hence, 138 plates are to be washed by her if she started at 7:15 and ends at 7:38, and the function will be f(x)=6x.
