Sagot :

Answer:

A. y = 0.005x + 350

B. 475 units

C. 600 units

D. $70,000

E. None of the above

Explanation:

A)

If the company spend $3,000 on advertisement then it can sell 15 additional units. Total the company can sell 350 units without any advertisement. Then assuming linear relationship the equation will be:

y = 15 /3000 x + 350

y = 1 / 200 x + 350

y = 0.005x + 350

B) y = 0.005 (25,000) + 350

y = 475

C) y = 0.005 (50,000) + 350

y = 600

D) $3,000 / 15 units = $200 per unit

Since 350 units are sold without any cost then additional 350 units will be sold by,

350 units * 200 $ = $70,000
