Each student that buys school lunch pays $2.75 the cafeteria typically brings between $1168.75 and $1438.25 how many students does the cafeteria typically serve

The Inequality modelling the equation is .

The cafeteria typically serve lunch for students between 425 to 523.

Step-by-step explanation:

Given:

Each students pays for lunch = $2.75

Cafeteria brings between $1168.75 and $1438.25.

We need to find the number of students cafeteria typically serve.

Solution:

Let the number of student served be 'x'.

Now we can say that;

Total money make is equal to Each students pays for lunch multiplied by number of students served.

But total money made is in the form of range so we can say that;

Now Dividing all sides by 2.75 we get;

Hence the Inequality modelling the equation is .

Hence we can say that, The cafeteria typically serve students between 425 to 523.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
