While shopping, Dawn finds a backpack that she likes on the sale rack. Its original price is $60,
but everything on the rack comes with a 30% discount. Dawn also has a coupon for 15% off of
her total purchase.
Dawn says, "Thirty percent and fifteen percent make forty-five percent and 45% of $60 is $33,
so it will cost $33."
Is Dawn correct? Explain why or why not. Be sure to support your reasoning with a
mathematical model.
Answers
Answer:
No, Dawn is not correct.
Step-by-step explanation:
I cannot provide you with a model, but the 30% discount should be applied first. 60*(70/100) = 42. Therefore, after the 30% discount, the cost will be $42. After that, Dawn should use her coupon. It will then get you 42*(85/100) = 35.70. Therefore, she would pay $35.70.

The original price of the computer is $500. The sales tax is 6%. What is the selling price of the computer?
Answers
Answer:
$530
Step-by-step explanation:
100 + 6 = 106
500/100 X 106 = 530
The selling price of the computer is $530
What is original price?"Original Price refers to the Fixed Price, Floor Price, Tunnel Price, the Premium or any other agreed upon price and established in the Confirmation."
What is sales tax?"Tax which is charged by the government on the of an item. The tax which is included in the prices is called Value Added Tax (VAT)."
We have
Original price of the computer = $500
Sales tax = 6%
Based on the given conditions
Formula for selling price with original price and sales tax
Selling price (OP with sales tax) = OP×( tax rate in decimal form+1)
Selling price (OP with sales tax) =500 × (6% + 1)
= 500 × (0.06 + 1)
= 500 × 1.06
= 530
Hence, The selling price of the computer is $530.

l=$45, P=$600, t=2 years What is the annual interest rate?
Answers
Answer:
The interest rate required to accumulate simple interest of $ 45.00 from a principal of $600.00 over 2 years is 3.75% per year.
Step-by-step explanation:
Given
l = $45
P = $600
t = 2 years
To determine
What is the annual interest rate = r = ?
Using the Simple Interest Formula
I = Prt
r = I/Pt
substituting l = 45, P = 600 and t = 2 years
r = 45 / ( 600 × 2 )
= 0.0375
converting r decimal to a percentage = 0.0375 * 100 = 3.75% per year
Thus, the interest rate required to accumulate simple interest of $ 45.00 from a principal of $600.00 over 2 years is 3.75% per year.

Answers
Answer:
3x+2y
Step-by-step explanation:
Find the rectangles attached
Area of a rectangle = Length * Width
A = A1+A2
given
A = 30cm²
A1 = 3 * x
A1 = 3x
A2 = 2*y
A2 = 2y
Substitute
30 = 3x+2y
Hence the required equation is 3x+2y = 30
Answer: 3x + 2y = 30
Step-by-step explanation:
A = L x W
The sum of the rectangle is 30.
One angle is 3 and x, the other one is 2 and y.
Multiply 3 with x = 3x.
Multiply 2 with y = 2y
Then create your equation plugging in 30 as the answer to 3x + 2y
After a 40% discount, the cost of a sofa is $471.00. What was the original cost of the sofa? NEED HELP ASAP
Answers
Answer: $659.40
Step-by-step explanation: You start with 471.00 X 0.4 which equals $188.40. So then you add $471.00 and $188.40 and you get $659.40!
The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
80% = $471
100% = $588.75
The original cost of the sofa is $588.75
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Original cost in percentage = 100% ____(1)
Cost after 40% discount = $471
This can be written as,
80% = $471 _____(2)
From (1) and (2) we get,
80% = 471
Multiply 100/80 on both sides,
100/80 x 80% = 100/80 x 471
100% = $588.75
Thus,
80% = $471
100% = $588.75
The original cost of the sofa is $588.75

Inga and Aileen are measuring the temperature of frozen hydrogen. Inga is using a thermometer that has increments of 0.25∘F, and she gets a measurement of 3.25∘F. Aileen is using a thermometer that has increments of 0.125∘F, and she gets a measurement of 3.375∘F.
Which thermometer has less uncertainty?
1. Aileen's thermometer, because it has smaller increments.
2. Neither, because the uncertainty in both thermometers is the same.
3. Inga's thermometer, because 3.25∘F is less than 3.375∘F.
4. Neither, because Inga and Aileen had different measurements.

Answer: AILEEN’S THERMOMETER, BECAUSE IT HAS SMALLER INCREMENTS
Step-by-step explanation:
I did the test and the attachment below is a screenshot of my test and I got 100%
Aileen's thermometer has less uncertainty because it has smaller increments. Option A is correct.
Given that,
Inga and Aileen are measuring the temperature of frozen hydrogen. Inga is using a thermometer that has increments of 0.25∘F, and she gets a measurement of 3.25∘F. Aileen is using a thermometer that has increments of 0.125∘F, and she gets a measurement of 3.375∘F.
All over the world, most things are in use as of common quantity, so people all over the world agree that they have to follow a common system of measurement and that the common system of measurement is called standard measurement.
Here,
Aileen's thermometer has a smaller increment than Inga's thermometer,
Because of the smaller increments, it has more chances to give precise measurements and less uncertainty.
Thus, Aileen's thermometer has less uncertainty because it has smaller increments. Option A is correct.
