iVinArrow [24]

Answer:

$14000

Step-by-step explanation:

Given parameters:

Amount earned by employee x  = $5250

Time duration  = 3weeks

Unknown:

Amount earned in 8 weeks = ?

Solution:

Let us first find the rate of employee x earning;

       Rate  = \frac{Amount earned}{Time duration}  

Insert parameters;

      Rate  = \frac{5250}{3}  = $1750/week

So,

  In 8 weeks;

      Amount earned  = rate x time duration

      Amount earned  =  $1750/week x 8weeks

      Amount earned  = $14000
