Answer:
The average number of Tv's sold was higher at store A than at store B
Step-by-step explanation:
You don't have to solve anything. They already gave you the mean/average. They just want to know who sold the most, so in this case you would just see who has the higher number, and see what answer matches.
Answer is in the attachment below.
Answer and Step-by-step explanation:
Alright, so when creating any type of math problem, it is important to identify the parts of the problem and where they go. First, we need to start by putting the problem together. We will use one of the most common forms of equations of math, also known as the linear equation of <em>y=mx+b.</em>
So we have: S(w)=__x + __. S(w) is also equal to f(x), which is also equal to y. So: y= __x + __.
Let's start filling this equation in. So, because it says that she will <em>add 25 dollars each week</em>, The problem is addition. Also, the 25 dollars each week will represent the mx in this situation. Here's why:
The x in this can stand for the amount of week she added this 25 dollars to her account. So:
y= 25x + __.
Now, we can add the 150 to the problem because that is what she started with for this one-time deal. So now we have:
y= 25x + 150.
You can now where everything is represented, but we are not done. Let's change y and x back into S(w) and w like the question asks us to have. So:
S(w)= 25w + 150.
If you want to solve this question, just replace the number of weeks in place of all w's in the equation, like this: S(2)= 25(2) + 150.
I hope that this helps.
Let x be the time for the AG800. Then the time for the AG950 is x + 20.
Cross-multiplying and simplifying, we get:
The positive solution to this quadratic is: x = 15.
The answer is: Time for model AG800 = 15 minutes: time for model AG950 = 35 minutes.
