What we know:
Yoko made $396 for 18 hours of work
What we have to find:
How much Yoko makes for 12 hours of work at the same rate.
What I did:
First I divided what she made by the hours to find our how much she made per hour.
396 / 18 = 22
Now we know she makes $22 per hour
I then times 22 by 12 hours
22x12 = 264
Answer:
Therefore Yoko made $264 for 12 hours of work
