Let the total amount earned at a given time be y, if x is the number of hours worked and amount earned per hour is $9, thus the equation representing this information will be:
Total amount earned=(number of hours)*(amount earned per hour)
hence:
y=9*x
y=9x
Answer y=9x

I'm not 100% sure about these. Just letting you know.
See, pls, the offered decision:
1. this ratio has another form: 2x/3x/4x;
2. the difference between the largest and the smallest is 4x-2x=10.
Then x=5, and the sequence of numbers is 10/15/20, where 15 is the middle number.
Answer: 15.
