Answer: 13.5 minutes
Step-by-step explanation:
Given : Sophie can type 128 words in 3 minutes.
Then , rate of typing = ![\dfrac{\text{Number of words}}{\text{Time}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BNumber%20of%20words%7D%7D%7B%5Ctext%7BTime%7D%7D)
(1)
Let x be the minute taken by her to type 576 words.
Then, rate of typing =
(2)
From (1) and (2), we have
![\dfrac{576}{x}=\dfrac{128}{3}\\\\\Rightarrow\ x=\dfrac{3\times576}{128}=13.5\text{ minutes}](https://tex.z-dn.net/?f=%5Cdfrac%7B576%7D%7Bx%7D%3D%5Cdfrac%7B128%7D%7B3%7D%5C%5C%5C%5C%5CRightarrow%5C%20x%3D%5Cdfrac%7B3%5Ctimes576%7D%7B128%7D%3D13.5%5Ctext%7B%20minutes%7D)
Hence, she will take 13.5 minutes to type 576 words.
A
40,000-31,850= 8,150times .25= 2,037.50
4,386.25+2,037.50= $6,423.75
