Last year Mr. Ingles total income was 52000+ total expenses were 53800 use expression I-E/12 where I represents total income in a represents total expenses to find the hours difference between his income and expenses each month and explain its meaning

-$150

Step-by-step explanation:

Given:

(I - E) / 12

Where,

I = total income

E = total expenses

I = $52,000

E = $53,800

(I - E) / 12

= (52,000 - 53,800) / 12

= -1,800 / 12

= -150

-$150 shows that Mr. Engle's total expenses exceeds his total income per month with an average of $150

 h = (S - 2πr²) / 2πr

Step-by-step explanation:

Since we are given that

S = 2πrh + 2πr²

Subtracting by 2πr² on both sides we get

S - 2πr² = 2πrh

Dividing by 2πr on both sides we get

(S - 2πr²) / 2πr = h

So

The final equation is

h = (S - 2πr²) / 2πr
