Answers
If stereo that normally sells for $125 is on sale for $90 then price of the stereo has been reduced by 28%.
What is Percentage?
percentage, a relative value indicating hundredth parts of any quantity.
To find the percentage reduction in price, we need to calculate the difference between the original price and the sale price
Divide the difference by the originalprice, and then multiply by 100 to express the answer as a percentage.
The reduction price is difference between the One hundred twenty five and ninety.
The reduction in price is:
$125 - $90 = $35
So, the stereo has been reduced by $35.
To find the percentage reduction, we divide the reduction by the original price and multiply by 100:
$35/$125 x 100%
0.28×100
When zero point two eight is multiplied with hundred we get twenty eight.
= 28%
Therefore, the price of the stereo has been reduced by 28%.

so you subtract $90 from $125 and that gives you $35, then you must determine the percentage by trial to see what percent that $35 is of $125, you can tell by looking that it will be near to a third or 33%, but not quite that much, so work backwards from there and try 30% and because that is just a bit more that $35, reduce and try a smaller percentage, 28% of 125 is exactly $35

D) f(n)= 4n-3
Answers
A) f(n) = 5n - 1
f(1) = 5(1) - 1 = 5 - 1 = 4
(1,4) ≠ (1,6)
Answer choice A is incorrect.
B) f(n) = 5n + 1
f(1) = 5(1) + 1 = 5 + 1 = 6
(1,6) = (1,6)
Answer choice B is correct.
C) f(n) = 4n + 3
f(1) = 4(1) + 3 = 4 + 3 = 7
(1,7) ≠ (1,6)
Answer choice C is incorrect.
D) f(n) = 4n - 3
f(1) = 4(1) - 3 = 4 - 3 = 1
(1,1) ≠ (1,6)
Answer choice D is incorrect.
Your answer is B) f(n) = 5n + 1
Answer:
B. f(n)= 5n+1

Answer:
$23.40
Step-by-step explanation:
Total money of William = Money from Lemonade + Money from Cookies
Money from lemonade:
It is given as $17.55
Money from cookies:
It is of money from lemonade. So we have;
So, $5.85 from cookies.
Hence, total money of William is $17.55 + $5.85 = $23.40
cookie+lemon=total
1/3 of 17.55=17.55/3=5.85
cookie+lemon=total
5.85+17.55=23.40
total made is $23.40

This is an example of renaming one-third to be three-ninths. The fractions are equivalent or equal, but the second fraction has a denominator of 9.
Sometimes when we subtract mixed numbers, we must rename the mixed numbers in a different way.
What does this mean? It means that when we are subtracting a mixed number from a whole number, we must rename to subtract correctly.
Let’s look at an example.
Example
6−456––––––––
In this example, we are trying to take a fraction from a whole number. We have to RENAME this whole number to do this.
How can we rename 6 to have a whole number part and a fraction part?
Think back. Remember when we learned that any fraction where the numerator and the denominator are the same that the fraction is equal to one?
1=44 or 33 or 55
Do you remember this? Well, if we can take one and rename it as a fraction, then we can use that to help us in our subtraction.
In the example above, we need to take 6 and make it a mixed number so that we can subtract. To do this, we borrow a one from the six and make it five. Then we take that one and make it into a fraction that has sixths as a denominator since that is the denominator of the fraction we are subtracting.
6=566
Next, we rewrite the problem.
Example
566−456–––––––– 116
This is our final answer..
Sometimes, we also have to rename a mixed number if the fraction we are subtracting is larger than the first fraction.
Example
619−349––––––
