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 formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
