The answer is 8.2 ^2 ......
$52.16
30% of 69 is 20.7.
69-20.7= $43.30
8% of 43.3 is 3.864.
43.3+3.864= $52.164
round down due to the 4.
$52.16

Answer:
Part a) 
Part b) 
Step-by-step explanation:
Part a) Create a linear equation
Let
t ----> the time in minutes
y ---> the temperature in °F
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem we have
The slope m is equal to

The y-intercept is

substitute

Part b) How many minutes until the water boils at 212° F?
For y=212° F
substitute in the linear equation and solve for t
