You get a 15% raise at you job and now make $13.50 per hour. What was you previous
Anna71 [15]

Answer:

Original wage was $11.74/hr

Step-by-step explanation:

Let your beginning hourly rate be r.  

Then 1.00r was your previous rate of pay.

Also, 0.15r was your pay increase.

Thus, 1.15r = $13.50.  Solve this for r:

r = $13.50 / 1.15 = $11.74/hr

Check:  Does $11.74 plus the raise 0.15($11.74) come to $13.50/hr?

                         $11.74/hr     +               $1.76/hr         =   $13.50.     YES

Solve the equation <br><br><br> 7a-3=11 a=4
irina [24]

Answer:

You cannot "Solve the equation" if it is written like that.

Step-by-step explanation:

If a=4 and the equation is 7a-3=11 then it is already solved or you typed it wrong or your teacher typed it wrong because if it was (7a - 3) then it would be 25 or if it was 7a(-3) it would equal -84
