Ana was washing dishes at the end of her shift at a restaurant. she washed 30 plates from 7: 30 to 7: 35. when she finishes washing all the plates, her shift will end. (
a. if she started washing plates at 7: 15 and ended at 7: 38, estimate how many plates she washed in total. explain your reasoning. (
b. write an equation to represent how many plates ana has left to wash at a particular time after her start at 7: 15. explain your reasoning.

There are 138 plates that are to be washed by her if she started at 7:15 and end at 7:38, and the function will be f(x)=6x.

Step-by-step explanation:

Since we have given that

She washed 30 plates from 7:30 to 7:35 ,

That means in 5 minutes , number of plates get washed by her = 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, number of plates get washed by her is given by

In 23 minutes, number of plates get washed by her is given by

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, there are 138 plates that are to be washed by her if she started at 7:15 and end at 7:38, and the function will be f(x)=6x.

answer: 2530

hope this
