A college entry exam has 38 questions worth 200 points. The test consists of multiple-choice questions, 𝑥

Question

x
, worth 4 points each and essay questions, 𝑦
y
, worth 10 points each.

is it
4𝑥+10𝑥=2004𝑦+10𝑦=38

4𝑥+10𝑦=384𝑥+10𝑦=14

4𝑥+10𝑦=38 𝑥+𝑦=200

or

4𝑥+10𝑦=200 𝑥+𝑦=38

this is the first time I've ever asked a question I have no idea how to do this please help, how do I do this math?

Answer 1

It says there are a total of 38 questions, x of which are multiple choice and y of which are essay type problems
or : x+y = 38

Now each of the x questions is worth 4 points, so you have 4x points
and each of the y questions is worth 10 points, so there are 10y points from there.
Is the total of those points not 200?
or 4x + 10y = 200

What matches that?
