Verified answer

Answer:

LETTER D (10)

Step-by-step explanation:

Equation: W = kNT

• w = work
• n = number
• k = constant
• t = time

Given:

• w = a job or 1
• n = 5 women
• t = time

First , we will solve for the constant k

• W = knt
• 1 = k(5)(8)
• 1 = k(40)
• 1/40 = k

Then , we will solve for the number

Given:

• W = 1
• n = number
• k = 1/40
• t = 4 days

Solving ,

• W = knt
• 1 = 1/40(n)(4)
• 1 = 4/40n
• 1 = 1/10n
• 1 ÷ 1/10 = n
• 1 × 10 = n
• 10 = n

Therefore , it will took 10 days
