Orlov [11]

Turn 45% into a decimal. You get 0.45, because you move the decimal two places to the left.

Then multiply 300*0.45
You get 135

Answer:

The correct option is A.

Step-by-step explanation:

If a line passes through two points $(x_1,y_1)$ and $(x_2,y_2)$ , then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Let y be the profit (in millions) after x years.

From the given graph it is clear that the line passes through the point (1,-100).

The company paid for these costs and made combined profits of $80 million after 4 years. It means the graph passes through the point (4,80).

The line passes through (1,-100) and (4,80). So, the equation of line is

$y-(-100)=\frac{80-(-100)}{4-1}(x-1)$

$y+100=\frac{180}{3}(x-1)$

$y+100=60(x-1)$

$y+100=60x-60$

Subtract 100 from both sides.

$y+100-100=60x-60-100$

$y=60x-160$

The function form is

$f(x)=60x-160$

Therefore, the correct option is A.
