Last year, mr. engle's total income was $52,000, while his total expenses were $53,800. use the expression i-e/12, where i represents total income and e represents total expenses, to find the average difference between his income and expenses each month. then explain its meaning.

The average difference in income and expenses each month is -150,

It shows every month the expenses is $ 150 more than income.

Step-by-step explanation:

Given formula of  average difference between his income and expenses each month,

    ( Suppose A )

Where,

I = total income,

E = total expenses,

We have, I = $ 52,000, E = $ 53,800,

Thus, by substituting the values,

The average difference in income and expenses each month,

Negative sign shows that the expenses exceed the income every month.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

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
