We could use the numbers and the difference of the original cost - the end price in a equation.
53 × x/100 = 15.9
Cross multiply 100 × 15.9.
53x=1590
Divide both sides by 53.
x=30

Answer:
slope m = 0
Step-by-step explanation:
To find the slope for two points, you need use
m = (y2 - y1)/(x2-x1)
for point 1 (-1, -4) and point 2 (-2, -4)
m = (-4 - (-4)) / ((-2)-(-1))
m = 0 / -1
when the top number is zero, the answer is 0
if you plot the points in a graph, it is a horizontal line or y = mx + b = 0m -4
y = -4
