Based on the double-line graph, in which year did sales of Product A first exceed those of Product B by at least $3 million?

  1. 2017
  2. 2018
  3. 2019
  4. 2020 (correct answer)

Explanation: Difference A − B by year: 2016 = −3-3, 2017 = −2-2, 2018 = 00, 2019 = +2+2, 2020 = +4+4. The first year the gap reaches at least 33 million is 2020. Earlier years fall short.
