Answer:
There are infinitely many solutions.
Step-by-step explanation:
3x + 2y = 7
-9x - 6y = -21
Now multiply the first equation by 3
3 × 3x + 2y = 7 ➡ 9x + 6y = 21 Now subtract second equation from first equation
9x + 6y - 9x - 6y = 21 - 21
0 = 0
The equation has infinitely many solutions meaning whatever value you write instead of x and y there will be solution.
50 employees work 40 hours/week at $20/hour.
Their combined regular hours salary is 50 * 40 * $20 = $40,000.
15 employees worked 4 hours at $30/hour.
Their combined overtime salary is 15 * 4 * $30 = $1,800.
The total payroll is the regular hours plus the overtime:
$40,000 + $1,800 = $41,800
The overtime is the following percentage of the total payroll:
$1,800/$41,800 * 100% = 4.3%
Answer: 4.3%
