Question

If there are 14 pens for every 3 pencils in a desk drawer, how many pencils would you expect if there were 100 pens? Round your answer to the nearest whole number. a. 30 b. 42 c. 21 d. 7

Answer 1

C. 21

Explanation:

Step 1: Set up an equation

• 
  `(14)/(3) = (100)/(x)`

Step 2: Cross-multiply.

• 
  `14 * x = 100 * 3`
• 
  `14x = 300`

Step 3: Divide both sides by 14 and round to nearest whole number.

• 
  `(14x)/(14) = (300)/(14)`
• 
  `x = (150)/(7)`
• 
  `x` ≈
  `21`

Therefore, the answer is C. 21.

Answer 2

21 would be the nearest whole number, i thinkn
