We are given the revenue function as:
R(x) = 11eaa894_649f_9e9a_a158_cff1b6e813ba_TB6775_11
where x is the advertising expenditure in billion dollars.
Substituting x = 5.8, we get:
R(5.8) = 11eaa894_649f_9e9a_a158_cff1b6e813ba_TB6775_11
≈ 1.527 billion dollars (rounded to the nearest billion)
Therefore, the revenue when $5.8 billion is spent on advertising is estimated to be 1.527 billion dollars, which corresponds to choice C.
