25% off translates into 0.25($30) = $7.50 off.
A faster way to determine the sales price is to subtract 0.25 from 1.00 and then mult. the regular price by the result: sales price = 0.75($30) = $22.50 (answer)
Therefore, f(x) = 2x + 3 is your derivative function, and you need to find the original curve. So find the antiderivative using the given conditions...
∫f(x) = ∫2x + 3 dx
F(x) = x^2 + 3x + C
2 = (1)^2 + 3(1) + C
2 = 4 + C
C= -2
Therefore, the curve is F(x) = x^2 + 3x - 2
Proof: The derivative is the slope at every (x, y) point. The derivative of F(x) comes out to be 2x + 3, so we have found the curve. Plug in x = 1, and y = 2, so the conditions have been met.

Answer: length = 28 feet
Width = 16 feet
Step-by-step explanation:
Let L represent the length of the rectangular garden.
Let W represent the width of the rectangular garden.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The perimeter of a garden is 88 feet. This means that
2(L + W) = 88
Dividing through by 2, it becomes
L + W = 44 - - - - - - - - - - - -1
The length is 12 feet greater than the width. This means that
L = W + 12
Substituting L = W + 12 into equation 1, it becomes
W + 12 + W = 44
2W + 12 = 44
2W = 44 - 12
2W = 32
W = 32/2
W = 16
L = W + 12 = 16 + 12
L = 28
