38 % of the total budget goes to advertising on broadcast TV
Solution:
Based on the details,
Expenditure for broadcast TV advertising = $ 22, 000
Expenditure for cable TV advertising = $ 30, 000
Expenditure for radio advertising = $ 6000
Need to determine: the proportion of broadcast TV advertising
Total expenditure = $ 22, 000 + $ 30, 000 + $ 6000
Total expenditure = $ 58000
proportion of broadcast TV advertising = 

Hence 38 % of the total budget is allocated to broadcast TV advertising
Answer:
The detailed work and solution can be found in the attachment
Step-by-step explanation:
Answer: F(x) > 0 in the ranges (-0.7, 0.76) and (0.76, ∞).
I hope this is useful:)
Try this approach (refer to the attachment, which outlines three steps).
To determine the slope, subtract the y coordinates from each other and the x coordinates as well. That gives us: 10000 - 4000 over 0 - 15, which simplifies to 6000 over -15. When divided, it results in -400. So, the slope amounts to -400. I hope this aids you!:D
