Question

BRAINLIST ANSWER- You and your friends want to rent a limo on prom night. The limo costs $75 per hour plus a $50 booking fee. You have $350 to spend. How many hours can you have the limo?(short explanation)

Answer 1

First, you would want to subtract the booking fee from the total amount of money you have to spend. 350-50 = 300. 
After paying the booking fee, you would have 300 dollars left to spend. Now, divide the amount of money you have left in all by the cost per hour. 300/75 = 4. 
The answer is B, because you can have the limo for 4 hours.
Hope that helped you.

Answer 2

Regardless of how many hours you rent the limo, you'll need to spend $50 to book it. That leaves you with $300. $300 divided by $75 is 4, so you can afford to have the limo for four hours.
