Answer:
Step-by-step explanation:
a) Percentage of potato filling = 100 - (30 + 25) = 100 - 55 = 45 %
b) Let the number of pies sold = x
45% of x = 90
Number of pies = 200
c) Number of cheese filling = 30% of 200
Number of beef pies = 25% of 200
Difference = 60 - 50 = 10
There are 10 more cheese pies than beef pies.
The total cost of hard drive is $29.96
Step-by-step explanation:
Given,
Original price = $40
Discount = 30%
Discount amount = 30% of $40 =
Discount amount=
Price after discount = Original price - discount amount
Price after discount = 40-12 = $28
Tax rate = 7%
Tax amount = 7% of price after discount
Total cost of hard drive = Price after discount + Tax amount
Total cost of hard drive = 28+1.96 = $29.96
The total cost of hard drive is $29.96

Answer:
The equation of the line in Point-Slope Form will be:
Also, check the attached graph below.
Step-by-step explanation:
Given the points
- C(2, -1)
- D(1, 1)
Determining the slope between the points C (2.-1) and D (1, 1).
- (x₁, y₁) = (2, -1)
- (x₂, y₂) = (1, 1)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [1 - (-1)] / [1 - 2]
= [1+1] / [-1]
= [2] / [-1]
= -2
Thus, the slope of the line = m = -2
The point-slope form of the line equation is defined as
where
- m is the slope of the line
- (x₁, y₁) is the point
In our case:
- (x₁, y₁) = (2, -1)
- m = -2
substituting the values m = -2 and the point (x₁, y₁) = (2, -1) in the point-slope form of the line equation
Therefore, the equation of the line in Point-Slope Form will be:
Also, check the attached graph below.
