Answer:
$400.00
Step-by-step explanation: The shirt was bought at 20% of its original value, or 1/5th. To calculate it's original value, we multiply it by it's inverse 5/1, which is 5 times it's sale price. <u>80 * 5 = 400.</u>
Part A
Let y = a + b*x
where
x = number of days
y = cost
When x = 2, y =$225. Therefore
a + 2b = 225 (1)
When x = 5, y = 480. Therefore
a + 5b = 480 (2)
Subtract (1) from (2).
3b = 480-225 = 255
b = 85
From (1), obtain
a = 225 - 2*85 = 55
Answer:
y = 55 + 85x
where x = the number of days
y = the cost (dollars)
Part B.
The cost is
f(x) = 55 + 85x
Part C
To graph y = 55 + 85x,
The y-intercept is 55
The x-intercept occurs when y = 0. That is
55 + 85x = 0
x = -55/85 = -11/17
The graph is shown below.
Check the picture below.
so the composite is just 2 triangles, one rectangle and one parallelogram.
we know the height and base of the triangles and length and width of the rectangle.
now, the parallelogram, we can simply split in in two triangles and a rectangle, like you see the split in the middle, and that gives us two more triangles and one rectangle.
so, we can simply get the area of each of those figures and sum them up, and that's the area of the composite.
