Can anyone help lend me a hand solving these problems please?​

well, let's see, what do we know about Timmy's Tubes, is a direct variation equation, since he's charging depending on the hours it's rented, thus

now, Fred charges $2 flat right off, plus $6.25 for every added hour, so Fred's equation will more or less be

1 hour2 + 6.25(1)

2 hours2 + 6.25(2)

3 hours2 + 6.25(3)

1)

how much will Timmy charge for 1 1/2 hour?

  or just 3.75

how much will Fred charge for the same time?

2)

using only $12 for each, who is the better bargain?

well, let's notice, Terri is going to get the same amount of hours with either, so, it really doesn't matter, both will only give 1.6 hours, or 1 hour and 36 minutes.
