Answer:
133°
Step-by-step explanation:
angles on a straight line = 180°
180 - 144 = 36°
angles in a triangle = 180°
36 + 31 = 67
180 - 67 = 113
answer = 113°

Answer:
The company should spend 20,000 dollars on advertising in order to avoid losing money.
Step-by-step explanation:
You know that the relationship between dollars spent on advertising X, and earnings P, for a particular company is:
P= 1.5* X -30,000
You want to know how much money the company should spend on advertising so that the company doesn't lose money. That is, the company has no losses but no profits. So this means that P must have a value of 0.
So, replacing:
0= 1.5*X - 30,000
Solving:
30,000= 1.5*X
30,000÷ 1.5= X
20,000= X

The company should spend 20,000 dollars on advertising in order to avoid losing money.</em></u>
