you start a business selling bottled fruit juices. You invest $15,000 for equipment. Each bottle cost $0.40 to make. You sell each bottle for $0.80. Write the equation on how you would solve to find how many bottles you must sell to earn a profit of $2,000. Let x be your variable

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.
