The price of a washing machine is reduced by 20% for a sale.
Afterwards, the sale price is increased by 30%.
Joachim says
The washing machine is now 10% more expensive than before the sale.
Explain Joachim’s error and work out the correct percentage change in the price of the washing machine from before the sale to after the sale
Answer:
1) Joachim's error is in applying the 30% increase to the initial price of the washing machine, 'x', rather than the reduced price of the washing machine for the sale, which is 0.8·x
2) The correct percentage change in price is 4%
Step-by-step explanation:
The price of the washing machine has the following parameters;
The percentage reduction of the price of the washing machine for a sale = 20%
The percentage by which the price is increased afterwards = 30%
Let 'x' represent the initial selling price of the washing machine before the price decrease, and let 'P' represent the sale price after the price increase, we have;
The price after the 20% reduction = x - 20% × x = x - (20/100) × x = 0.8·x
The price after the 30% increase after the sale = 0.8·x + 30% × 0.8·x = 0.8·x + 30/100 × 0.8×x = 0.8·x + 0.3 × 0.8·x = 1.04·x = x + 0.04·x = x + (4/100) × x = x + 4% × x
Therefore, Joachim's error is in applying the 30% increase to the initial price of the washing machine, 'x', rather than the reduced price of the washing machine for the sale, which is 0.8·x
2) The percentage change in the price after the sale is given as follows;
Price of the washing machine after the sale, P = 1.04·x = (104/100) × x = 104% × x
∴ P = 100%x + 4%x = (100/100)·x + 4%x = x + 4%
The percentage change in price = P - x = x + 4% - x = 4%
The correct percentage change in price = 4%

Answer:
-4.65< -4 and 2/5
Step-by-step explanation:
To solve, this we can convert the fraction -4 and 2/5 into a decimal so that the values can be more easily compared. When we do this, we get the result that -4 and 2/5 equals -4.4. Now we can clearly see which value is greater because they are written in the same form:
-4.65<-4.4
-4.65<-4 2/5
Answer:
<
Step-by-step explanation:
You have to convert the mixed number by multiplying the whole number by the denominator, adding the numerator, and dividing the sum by the denominator.
4x5=20
20+2=22
22÷5=4.4
-4.65 < -4.40
After 14 years, I shall be three times as old as I was 4 years ago. What is my present age?
Answer:
Present age = 13 years
Step-by-step explanation:
Let the present age be x years.
14 years after age = (x + 14) years
4 years ago age = (x - 4)
According to the given information:
14 years after age = 3 times 4 years ago age
x + 14 = 3(x - 4)
x + 14 = 3x - 12
14 + 12 = 3x - x
26 = 2x
x = 26/2
x = 13 years
Thus, the present age is 13 years

366$ per month
Step-by-step explanation:
To get the answer you know that you are paying 252 evey month for the car payment and 684 every 6 month so yo take the 684 and divide it by 6 to get how much you pay each month and add it to the 252 and that's your answer of 366$
On a recent day, 8 euros were worth $9 and 40 euros were worth $45. Enter an equation of the form y = kx to show the relationship between the number of euros and the value in dollars. Let y be the value In dollars and x be the number of euros. The equation is y =
Answer: y = 1.125x
Step-by-step explanation:
Divide the amount in dollars by the number of euros.
9/8 = 1.125
45/40 = 1.125
Since the constant change is 1.125, the input the 1.125 into the formula y=kx for k to get the equation y = 1.125x

An 11-m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 14 m. Find the length of the shadow. If necessary,
round your answer to the nearest tenth.
14
11
?
Answer:
8.66 m
Step-by-step explanation:
Given that,
The distance from the top of the building to the tip of the shadow is 14 m
The height of the building is 11 m.
We need to find the length of the shadow. we can see that the length of the shadow forms the base of the triangle.
The distance from the top of the building to the tip of the shadow form hypotensue and height of the building forms perpendicular. So, we can use Pythagoras theorem to find the base.
So,
[tex]H^2=b^2+h^2\\\\b^2=H^2-h^2\\\\b=\sqrt{14^{2}-11^{2}}\\\\b=8.66\ m[/tex]
So, the length of the shadow is 8.66 m.

There are 2 rectangles. One was 1.2 cm by 3.4 cm. The other was measured 2.1 cm by 1.7 cm. How much is the perimeter?
Answer: See explanation
Step-by-step explanation:
Perimeter of a rectangle is given as:
= 2(length + breadth)
First rectangle measures 1.2 cm by 3.4 cm. The perimeter will be:
= 2(1.2+ 3.4)
= 2(4.6)
= 2 × 4.6
= 9.2cm
Second rectangle measured 2.1 cm by 1.7 cm. The perimeter will be:
= 2(2.1 + 1.7)
= 2 × 3.8
= 7.6cm
Total perimeter = 9.2cm + 7.6cm = 16.8cm
