Me. abby, julia, kim, and jeanie had collected donations following a walkathon. abby had collected 3 times as much as julia. kim had collected $25 less than abby. jeanie had collected twice as much as abby. then jeanie received a check from her grandmother for $55, which gave her the same combined total amount that abby, julia, and kim had collected. find the amount that julia collected.

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
