Store W- $5 unlimited copies and Store Z- 20cents/copy + $2 machine use The total cost, c, of making n copies can be represented by a system of equations. A. estimate how many copies you need to make for the total cost to be the same at both stores B. if you have to make a small number of copies, which store should you go to? explain

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
