To earn a profit, the revenue must be greater than the cost. the revenue for selling x units of an item is r = 26.05x. the cost to make x units is c = 1,500 + 16.75x. the owner claims she had a profit today because they made and sold 183 units of the item. is her claim true? yes, because r > c when x = 183. yes, because r < c when x = 183. no, because r > c when x = 183. no, because r < c when x = 183.

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
