A car wash charges two prices depending on the size of the vehicle. The table shows the number of cars washed, the number of SUVs washed, and the total earnings for the past 2 hours.

Each car costs the same price, and each SUV costs the same price.

The system of equations can be used to represent the situation.

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
