The price of the original shirt is $45, it is reduced to $32.50. Calculate the percentage decrease. Show your workings.
Answers
Answer:
The percent decrease in the price of shirt is 27.78%
Step-by-step explanation:
The percent decrease is the decrease in the price of a product or good.
Given
Original Price = $45
Decreased price = $32.50
Percentage decrease is calculated by using the formula
[tex]Percentage\ decrease = \frac{decrease}{Original\ price} *100\\[/tex]
And the decrease is calculated as:
[tex]Decrease = Original\ price - Reduced\ price[/tex]
So,
[tex]Decrease = 45-32.50 = 12.5[/tex]
Putting the values in the formula for percent decrease
[tex]Percent\ decrease = \frac{12.50}{45} *100\\=0.2777..*100\\= 27.77..[/tex]
Rounding off to nearest hundredth: 27.78%
Hence
The percent decrease in the price of shirt is 27.78%

The equation of the line is y
Answers
Answer:
y = 5x-14
Step-by-step explanation:
We should use point-slope form to form our equation:
y-1 = 5(x-3)
y-1 = 5x-15
y = 5x-14
Our equation is now in slope-intercept form.

The number of pens sold on Monday, p, increased 45% on Tuesday. The expression p+0.45p represents the number of pens sold on Tuesday. What is another expression that can be used to find the number of pens, p, sold on Tuesday?
Answers
Answer:
1.45p
Step-by-step explanation:
Here, we want to write another expression other than what we have already to represent a 45% increase in the number of pens sold
We simply find 45% of the number of pens sold the previous day
Mathematically, that would be
45/100 * p = 0.45p
we now add this to the sales made the previous day
= p + 0.45p
if we finally add both, we will have p(1 + 0.45)
= 1.45p
