Example: Translating and Solving a Profit Inequality for a Service Business

To determine the required hours of work to achieve a profit goal, translate the problem into an inequality. For example, if a pet sitting business charges $32 per hour, has monthly expenses of $2,272, and aims for a profit of at least $800, let hh be the number of hours worked. The profit inequality is 32h2,27280032h - 2{,}272 \geq 800. Adding 2,2722{,}272 to both sides yields 32h3,07232h \geq 3{,}072. Dividing by 3232 gives h96h \geq 96. Therefore, at least 96 hours must be worked to earn the target profit.
