gina rented a moon walk for 5 hours at total cost of $230. lori rented the same moon walk for 2 hours at a total cost of $125. t
aleksklad [387]
Assuming both rented from the same store and the rental price is the same.

$230 -  $125 = $105
5hours - 2hours = 3hours
3hours = $105
1 hour = $105 ÷ 3 = $35
So the price of 1 of one hour rental is $35.

2hours = $35 x 2 = $70
Lori paid $125
Therefore the flat setup fee = $125 - $70 = $55

Ans:  Setup fee = $55, rental fee = $35/hour

On Monday, you realize that a significant theft occurred between 6PM Friday and 8AM Monday. You have good video tape of the time
Sergeu [11.5K]

For this one, find out how many hour have passed per day with 6 pm Friday being where you start.  

6 pm Friday- 6 pm Saturday =24

6 pm Saturday - 6 pm Sunday= 24

6 pm Sunday - 6 am Monday = 12 hours

6 am Monday until 8 am Monday= 2 hours


Now just add the amount of hours together

24+24+12+2= 62 hours

Now convert that to minutes.

There are 60 minutes in 1 hour.  You multiply the amount of hours by 60 to get the minutes.

62 hours times 60 minutes in 1 hour

62*60= 3720.

So you will have a total of 3,720 minutes of tape to review.
