Answer:

230 were sold at the door

170 were sold in advance

Step-by-step explanation:

i'm not entirely sure  if this is the proper way to do it but it has the correct answer:

x=at door y=in advance

x+y=400

3x+2y=1030

y=-x+400

2y=-3x+1030

y=-3/2x+515

-x+400=-3/2x+515

x=230 y=170

hope this helps :) have a nice day !!

Answer: OPTION B

Step-by-step explanation:

Let's call:

c: the number of cars.

m: the number of motorcycles.

Based on the given information, you can set up the following system of equations:

\left \{ {{c+m=38} \atop {4c+2m=104}} \right.

You can solve it by the Elimination method:

- Multiply the first equation by -4.

- Add both equations to cancel out the variable "c".

- Solve for "m":

\left \{ {(-4)(c+m)=38(-4)} \atop {4c+2m=104}} \right.\\\\\left \{ {-4c-4m=-152} \atop {4c+2m=104}} \right.\\-------\\-2m=-48\\m=24

(24 motorcycles)

 - Substitute m=24 into any of the original equations ans solve for "c". Then:

c+24=38\\c=38-24\\c=14

(14 cars)
