a. 20h - 645 = 555

b. Ozzie will work more than equal to 60 hours.

Step-by-step explanation:

Ozzie plans to earn $20 per hour.

Expenses of Ozzie (per month)

Overhead = $500

Fax and phones = $120

Materials = $25

Total expenses per month = (500 + 120 + 25) = $645

a. Let Ozzie works h hours to earn a profit of $555.

monthly earning = 20h

equality for the profit will be

20h- (total monthly expenses) = 555

20h - 645 = 555

b. To get the profit of $555 at least, numbers of hours Ozzie will work will be represented by the term

20h - 645 ≥ 555

20h ≥ 555 + 645

20h ≥ 1200

h ≥

h ≥ 60

Ozzie should work more than 60 hours to earn profit at least  $555.
