Given: ABCD is a parallelogram with diagonals AC and BD intersecting at M. Prove: Segment DB and Segment AC bisect each other.

Please complete the proof by providing the reasons for each statement ABCD is a parallelogram with diagonals AC and BD intersecting at M.
Segment AB||Segment CD,
Segment BC||Segment AD
Segment AD ≅ Segment CB, Segment AB ≅ DC
∠DBA and∠BDC are alternate interior angles
∠DBA≅∠BDC
∠CMD and∠AMB are vertical angles
∠CMD ≅ ∠AMB
ΔCMD ≅ ΔAMB
Segment AM ≅ Segment MC
M is the midpoint of Segment AC

First, you need to find out how much will the candle cost per volume. If a candle with a volume of 80cm^3 costs $12, the price of the candle per cm^3 would be: $12/80cm^3= $0.15/cm^3

Then the price of a candle with 120 cm^3 volume would be:120cm^3* $0.15/cm^3= $18
