4. For the three-step question that follows, provide your answer to each question in the given workspace. Identify each step with a coordinating response. Be sure to clearly label each part of yo response as Part A, Part B, and Part C.

Part A: Ava was asked to find the value of the expression 13t - 8r2 when t = -10 and r =

2. Her work is shown below, but she made a mistake. What was Ava's mistake?

13t - 8r2

13( - 10) - 80 - 2)

131 – 10) - 804)

130 - 8(4)

-138 - (4)

-552

Part B: Evaluate the expression correctly.

Part C: Show all of your work to support your answer to Part B.
