There is only 1 solution. Answer is 2. İ solved it you can check below
Answer:
The water is 208.22ft from the tug boat
Step-by-step explanation:
The governing equation is
y is the height above the ocean
x is the distance from the tugboat
if y= 6ft, the equation will now become
we can arrange this properly to form a quadratic equation by grouping like terms.
solving quadratically we have two values of x as 208.22ft and 0.873 ft.
We can take a more realistic value as a solution to our problems:
208.22ft
The equation is: (y+3)/(-1+3) = (x-5)/(3-5);
Then, (y+3)/2 = (x-5)/(-2);
Finally, y+3 = -x+5;
y = -x + 2;
It would be 50 times 0.075=3.75 sales tax and add that to the cost of the earrings =$53.75
