A robot vacuum cleans a dirty floor using multiple passes. During each pass, 25% of the dirt is removed. If the floor initially has 20.00 oz of dirt, how much dirt will remain after 6 passes?
A) 20 x 0.87^6 ≈ 8.67 oz
B) 20 x 0.750^6 ≈ 3.56 oz
C) 20 x 0.94^6 ≈ 13.80 oz
D) 20 x 0.92^6 ≈ 12.13 oz

Respuesta :

The equation that can be used to determine the amount of dirt on the floor after 6 passes is 20 x 0.750^6 ≈ 3.56 oz.

What is the equation ?

The equation that can be used to determine the amount of dirt left after 6 passes is an exponential equation. Exponential equations have the form:

Amount of dirt left = p(1 - r)^n

Where:

  • p = initial amount of dirt
  • r = rate at which dirt is removed with each pass
  • n = number of passes

20(1 - 0.25)^6

20(0.75^6) = 3.56 oz
