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
