Answer:
78%
Explanation:
Able has an awareness level of 78%.
Next year, it will lose a third of its awareness level.
78% * 1/3 = 26%
78% - 26% = 52%
So the base awareness level of able for next year will be 52%, however, even if the company reduced the promotion budget, it still has 1 million dollars to invest, and the question is telling us that 1 million in promotion investment results in a 26% increase in awareness, therefore
52% + 26% = 78%
Thus, after investing the 1 million dollars, Able's awareness level next year will be the same as the current year: 78%
