Based on the graph showing point ( 38, 29.94) and the given slope of -0.13, we can use can use the point-slope formula to determine the equation of the line:

y- 29.94 = -0.13(x- 38)

y - 29.94 = -0.13x + 4.94

y = -0.13x +34.88

So, for 23 minutes we plug it into x:

y = -0.13(23) + 34.88

y = $31.89
