Answer:
x = 5
y = 7
Step-by-step explanation:
See the image that I have added to you above to get the whole working.
Assuming that this field is rectangular with 2 semi-circles (one on both ends of the field), we must first calculate the total area of the field. this is done by adding the area of the rectangular portion and the circular portion. This is done below:
Given:
Rectangular length = 95 yards
Rectangular width = semi-circle diameter = 49 yards
Area of rectangle = length * width = 95 * 49
Area of rectangle = 4655 yd^2
The area of the 2 semi-circles can be obtained by treating both as one circle.
Area of circle = pi * (d/2)^2 = 3.1416 * (49/2)^2
Area of circle = 1885.74 yd^2
Total area = 1885.74 + 4655 = 6540.74
We multiply the area by the cost of fertilizing:
Total cost = cost per sq. yd * total area
Total cost = 0.08 * 6540.74
Total cost = $523.26
Answer:
r = 2.75
Step-by-step explanation:
1.25 + r = 4
Subtract 1.25 on both sides.
1.25 + r - 1.25 = 4 - 1.25
r = 4 - 1.25
r = 2.75
The solution to the equation is r = 2.75.

First find what one percent is. Then multiply it by 15 (your markup). Then add it to your original price.
