Q10. 

Let's find a conclusion having statements step by step.

a) If 3 cans of soup cost a total of $0.85, then 1 can of soup costs:

\frac{\$0.85}{3}

b) If I get n cans of soup the equation I need to use is multiply the previous equation by n:

(\frac{\$0.85}{3})n

The conclusion is: G. Multiplying n by the cost of 1 can.

Q11. 

Let's find a conclusion having statements step by step.

a) The company charges $40 to hook a vehicle, so this is a constant variable. Then:

c = 40$

b) There is a second statement that states that for each mile the vehicle is towed the cost increases $1.70, so:

c = $40 + 1.70m

So, the answer is B.

Answer: 2,215,000

Step-by-step explanation:

Given: The quadratic function f (x) = - 45x^2 + 350x + 1,590 models the population of a city where x represents the number of years since 2005.

To Find:  population of the city in 2010

We need to put x= 2010-2005 = 5

f (5) = - 45(5)^2 + 350(5) + 1,590\\\\=-1125+1750+1590 =2215

Hence, the estimated population of the city in 201 = 2215 thousands or 2,215,000 .
