32.75 + 39.88 = 72.63

72.63 x 114% = 72.63 x 1.14 = $82.7982 or $82.80 to the nearest cent.

114% is all of the cost of the meal plus 14 % extra for the tip. See how muliplying by 1.14 includes the $72.63 (this saves the step of adding it on at the end if you were only to find 14% of $72.63)

What is the equation of the graph????

tia_tia [17]

The graph shown above is a "parabola" and the parent function is x². So, we can start off at x². The graph of x² intersects the x and y-axis at (0, 0). In this case, it's simply being shifted up by 1 and intersects the x and y-axis at (0, 1). Therefore, the equation is:
$y = x^2 + 1$

To check, let's plug in 0 for x, and see what we get (we should get 1):
$y = x^2 + 1$
$y = 0^2+1 = 0+1=1$

We are right, so your final answer is x² + 1.
