Discounts are used to reduce the original price of an item.
David will pay $25 and 92 cents for an item of $32, before tax
The discount (d) is given as:
The price (p) of the item is given as:
So, the amount (A) paid before tax is calculated using:
Substitute known values
Express percentage as decimal
Subtract 0.19 from 1
Multiply 32 and 0.81
Hence, David will pay $25 and 92 cents for an item of $32, before tax

The first step is to determine how accurate your estimation needs to be. Then create the iniatial estimate.
Since A (area of circle = C) is given = 148
Where we assume:
Y represents radius of the circle (r)
X represents diameter of the circle (D)
Pi (π) = 3.14
A = 2 * π * y
148 = 2 * 3.14 * y
148 = 6.28 * y
y = 148/6.28
So, y = 23.56
D = 2 * y
D = 2 * 23.56
So, D = 47.12
Assume A is unknown (not given as 148)
A = π * y^2
A = 3.14 * (23.56)^2
A = 3.14 * 47.12
So, A = 147.95 (approx. A = 148)
C- is either a or c
