Step-by-step explanation:

\overline{DA} \text{ bisects } \overline{EB}     is given

\overline{BC} \cong \overline{EC}  definition of <u>bisect</u>

<u />\overline{EB} \perp \overline{ED}, \, \overline{EB} \perp \overline{BA}  are both given

<u />\angle B, \, \angle E \text{ are right angles}  definition of perpendicular

\angle B \cong \angle E   because all right angles are congruent

\angle{ACB} \cong \angle{DCE}  vertical angles are congruent

\triangle{ACB} \cong \triangle{DCE}   ASA (angle-side-angle)

\overline{ED} \cong \overline{BA}  CPCTC (corresponding parts of congruent triangles are congruent)

8.75 x 11 = 96.25

So, if Paula works for 11 hours,  she will earn $96.25!
