work too many times. His total weekly pay, y, is represented by the equation

Answer:

2.50$

Step-by-step explanation:

y=20(10.50-x).

160 = 20 (10.50-x)

160 = 210 - x

160 - 210 = -x

-50 = -x

50 = x

50$ Is the total per week, divided by the number of hours 20. You’ll have the cut per hour.

50/20 = 2.50

Answer:

x = $2.50

Step-by-step explanation:

y = 20(10.5 - x)

$160 = 20(10.5 - x )        {use distributive property}

160   = (20*10.5) - (20*x)

160   = 210 - 20x      {Add 20x to both sides}

160 +20x = 210             {Subtract 160 from  both sides}

        20x = 210 - 160

        20x = 50

            x = 50/20

             x = $2.50
