## College Algebra (6th Edition)

We test whether the coordinates of B$=(76,220)$ satisfy BOTH inequalities. Inequality 1: $5.3(76)-220 \geq 180\quad?$ $182.8 \geq 180\quad?$ Yes. Inequality $2$: $4.1(76)-220 \leq 140\quad?$ $91.6 \leq 140\quad?$ Yes. Both inequalities are satisfied. B belongs to the solution set.
