Answer:

$432.18

Step-by-step explanation:

Time and a half = 50% more pay rate / 1.5*6.86 = $10.29 per hour

Double time = 2*6.86 = $13.72 per hour

Rest of the time => At regular rate

Total Amount = 10(10.29) + 4(13.72) + (54 - 10 - 4)(6.86)

= 10(10.29) + 4(13.72) + (40)(6.86)

= $ 432.18

How many solutions are there to the<br>system of equations, x + y = 1<br>and 2x + 2y = 2?

larisa86 [58]

There are infinitely many solutions of the system of equations, x + y = 1

and 2x + 2y = 2

Step-by-step explanation:

We need to find how many solutions are there to the system of equations.

$x+y=1\,\,\,(1)\\2x+2y=2\,\,\,(2)$

Solving:

Multiply equation (1) with 2 and subtract with equation(2)

$2x+2y=2\\2x+2y=2\\-\,\,-\,\,\,\,\,\,\,\,\,\,\,\,-\\------\\0=0$

Since our answer is 0=0 so, there are infinitely many solutions.
