Answer:

E(119.5)= 730m

Step-by-step explanation:

Given

E(t)= 1200(120-t)+520(120-t)^2

Required

Determine E(119.5)

E(t)= 1200(120-t)+520(120-t)^2

Simply substitute 119.5 for t

E(119.5)= 1200(120-119.5)+520(120-119.5)^2

Evaluate the expressions in bracket

E(119.5)= 1200(0.5)+520(0.5)^2

Solve 0.5²

E(119.5)= 1200 * 0.5+520*0.25

E(119.5)= 600+130

E(119.5)= 730

Hence;

E(119.5)= 730m

With no advertising your newspaper has a circulation of 6000 papers. For each dollar you spend on advertising, your newspaper ci
Brilliant_brown [7]

Answer:

Step-by-step explanation:

First, the profit formula:

PROFIT= TOTAL REVENUE - TOTAL COST

Next, note the points:

- Without Advertisement, Q = 6,000 where Q is quantity supplied

- A formula that gives the total profit P in dollars must take into account that 100cents = 1dollar

- Here, only a dollar is spent on advertisement, hence, Q = 6005

- Advertising expenses have been accounted for and [P = 9cents × Q] where Q is quantity sold.

- 9 cents = 0.09 dollars

TOTAL PROFIT FORMULA = 0.09Q - 500
