Answer:
$12.00
Step-by-step explanation:
If they paid $0.72 in tax and tax is 6% or .06 then you could create an equation like this: x * .06 = .72 with x representing the original cost of the bracelet. Now you can just solve for x like so:
x * .06 = .72
÷.06 ÷.06
x = 12
To find the rate of change, also known as the slope, we can use the slope formula with these two given points.
Point 1: (20, 25)
Point 2: (50, 40)
(40 - 25) / (50 - 20)
15 / 30
0.5
The rate of change of this function is $0.50 / lb.

= 4 π (40 m)²
= 4 π (1600 m²)
= 6400 π m²
