Employee x earned $5250 in 3 weeks. at this rate how much will employee x earn in 8 weeks

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
