A car rental costs a fee of $150 plus $35 per
lutik1710 [3]

Answer:

5 hours

Step-by-step explanation:

We know that Joey spent a total of $325. He first paid the fee of $150. Let's subtract $150 from $325.

$325 - $150 = $175

Now, we know that it costs $35 per hour to rent the car. So, we divide $175 by $35 to find out how many hours Joey rented the car for.

$175 ÷ $35 = 5 hours

Louann and Carla received equal scores on a test made up of multiple choice questions and an essay. Louann got 14 multiple choic
Gnoma [55]
Louann= 14x+24
Carla= 16x+14
 So basically this is just like solving equations. The way I did this was just put random numbers for x and then solve it.
First attempt: 
14(7)+24=16(7)+14
98+24=112+14
122=126
 Okay the first one didn't work so I use 6 for x. 
Second attempt: 
14(6)+24=16(6)+14
84+24=96+14
108=110

So 6 didn't work and you already should know that the answers should be between 1 and 5. 

So now I going to do 5 for x
Third attempt:
14(5)+24=16(5)+14
70+24=80=14
94=94
 
And so the answer is 5! :D The multiply choice questions were worth 5 points and Louann and Carla had 94 for their scores! I hope this help you out and clear for you! :D
