Answer:
$24,893.40
Step-by-step explanation:
Year 1
50,000 x 0.16 = 8,000
50,000-8,000 = 42,000
Year 2
42,000 x 0.16 = 6,720
42,000-6,720 = 35,280
Year 3
35,280 x 0.16 = 5644.80
35,280-5644.80= 29,635.2
Year 4
29,635.2x0.16 = 4,741.6
29,635-4,741.6 = $24,893.40

Y-y1=m(x-X1) is the formula.
m is the slope and the y1 and x1 are your points.
leave x and y; the ones without the 1 and solve for y
