Answer:

Option A.

Step-by-step explanation:

Base cost of the survey is defined by the expression

Base cost C = 850 + 4.5x

where x = number of persons surveyed

If the budget to spend on a survey is = $3000

Then Number of person we can survey can be determined by

3000 = 850 + 4.5x

4.5x = 3000 - 850

4.5x = 2150

x = \frac{2150}{4.5}

x = 477.78

But the number of persons surveyed can not be in fraction.

Therefore, sample size we can afford is 477.

Option A. is the answer.

SOLUTION

Given the question in the question tab, the following are the solution steps to get the rental cost for each movie and each video game.

Step 1: Write the representation for the two rentals

Let m represents movies

Let v represent video games

Step 2: Write the statements in form of a mathematical equation

\begin{gathered} \text{Month 1: }4m+8v=57 \\ \text{Month 2: }2m+3v=23 \end{gathered}

Step 3: Solve the equations above simultaneously using elimination method to get the values of m and v

\begin{gathered} 4m+8v=57----(1) \\ 2m+3v=23----(2) \\ \text{ multiply equation 1 by 2 and equation 2 by }4 \\ 8m+16v=114----(3) \\ 8m+12v=92----(4) \\ \text{subtract equation (4) from equation (3)} \\ 4v=22 \\ v=\frac{22}{4}=5.5 \\ \text{Substitute 5.5 for v in equation 1 to get the value of m} \\ 4m+8v=57 \\ 4m+8(5.5)=57 \\ 4m+44=57 \\ 4m=57-44=13 \\ m=\frac{13}{4}=3.25 \\ m=\text{\$}3.25,v=\text{\$}5.50 \end{gathered}

Rental cost for each movies is $3.25

Rental cost for each video games $5.50

Add. Simplify. Please HELP!!!
Archy [21]

Answer: the first answer is 8 and 5/8, #2, (bottom left) is 17 and 6/10. #3, (top right) is 6 and 3/8. #4, (bottom right) is 19 and 3/10.

Step-by-step explanation: to add fractions, you have to have a common denominator. to get a common denominator, you multiply one or both sides to make the same number on the bottom. when you multiply the bottom, you also have to multiply the top. After that, you add the top numbers and add the whole numbers next to it. Then you just put the numbers together.

Hope this helps! if it is wrong, could you please correct me.
