The discount would be $77.5 as 310 divided by .25 is 77.5.
Answer:
it has to be D for sure trust me
<u>Statement Reason </u>
MP || NS; RS || PQ; MR ≅ NQ Given
m∠3 = m∠2 Alternate Interior Angle
m∠1 = m∠4 Alternate Interior Angle
MQ = MR + RQ Segment Addition Postulate
NR = NQ + RQ Segment Addition Postulate
RQ = RQ Reflexive Property
MR = NQ Definition of ≅
△MQP ≅ △NRS ASA ≅
