Algebra Questions! Please Help!?

1. Shannon and Macie are raking leaves to earn some money. Shannon can rake 2 lawns that are about the same size in 5 hours. Jackie can rake 2 lawns that are about the same size in 6 hours. How long would it take both girls to work together to rake 2 lawns? Write and solve an equation for this situation. Explain how to set up the equation, using w = rt.
2. Bob has two savings accounts. He deposited $100 more into account B than account A. After a period of time, account A has earned $105 in interest at 7%, and account B has earned $80 in interest at a rate

Bob has two savings accounts. He deposited $100 more into account B than account A. After a period of time, account A has earned $105 in interest at 7%, and account B has earned $80 in interest at a rate of 5%. 
Write an equation to represent the situation. Explain each variable used. 
How much money did Bob initially deposit into each account? Solve the equation

roadjester · Answer

x*.07=105
(x+100)*.05=80

roadjester · Answer

I think that's accurate, but I haven't solved something like this in a long time
x represents the original amount deposited.

ok thank you... do you have any clue on the first one?

roadjester · Answer

correction, w=rt. I'm assuming rate*time.

roadjester · Answer

but what does w stand for?

anonymous · Answer

yes but i think w stands for the lawn they are raking and they are raking one lawn so mabye w=1?

anonymous · Answer

yah i just looked it up aand the w means the amount of jobs they are doing so w = 1 lawn

roadjester · Answer

Sry bout that, helping someone else. Anyway, If you divide by 2 for each girl, Shannon can rake one lawn in 2.5 hrs. Marcie can rake one lawn in 3 hrs. I really hate these types of questions where you have to combine the work two people can do. However, I'm pretty sure on question 2.
