Question 436964: Bill earns $3 more per hour than Sally. Last week, Sally worked 10 more hours than Bill. If they both earned $600 last week, what is Sally's hourly rate?
I can't figure out the connection to other variables to set up my equation.
I have this so far:
Let Bill's rate = R sub b (D sub b / H sub b)
Let Bill's dollars = D sub b (D sub s +3)
Let Bill's hours = H sub b (H sub s -10)
Let Sally's rate = R sub s
Let Sally's dollars = D sub s
Let Sally's hours = H sub s
I don't know where to go from here.

Question 437181: Here's the question: "A motorcycle travels 40 miles in the same time that a bicycle travels 15 miles. If the bike travels 20 miles per hour slower than the motorcycle, find the speed of the bike"
I've tried setting it up with this equation:
40+15=x-20
then solved.
55=x-20
35=x
I'm just not entirely sure that I have the equation set up right.
