$19,297 is invested, part at 13% and the rest at 8%. If the interest earned from the amount invested at 13% exceeds the interest earned from the amount invested at 8% by $777.58, how much is invested at each rate? (Round to two decimal places if necessary.)

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
