work:

First set up your proportion

part. 53. x

= =

whole 100. 2700

I'm choosing to cross multiply but there are different methods

so 100x= 143100

then you have to get x by itself so you divide each side by a hundred and x= 1431

here ya go

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
