e-lub [12.9K]

Solution:

<u>Note that:</u>

  • Men:Woman = 3:2
  • 54 women = Total woman in a company

<u>3:2 can also be written as 3x:2x.</u>

  • => Men:54 = 3x:2x

  • => x = 27
  • => Men = 3x
  • => Men = 3(27) = 81
  • => Total employees: 81 + 54
  • => Total employees: 135

There are 135 employees in total.

2. In the ratio of 3:2:2, three brothers invested a total of 249,000 to open a store. Find each
GaryK [48]

Answer:

$106,714.29

$71,142.86

$71,142.86

Step-by-step explanation:

There's a total of 7 pieces that they invested (3 + 2 + 2 = 7) so you can do 249,000 / 7 to find what each piece was worth.

249000/7 = about 35571.43

(you always have to round money to 2 decimal places)

Then the amount each brother spent would be:

3 * 35571.43 = 106714.29

2 * 35571.43 = 71142.86

2 * 35571.43 = 71142.86
