Your math test has 38 questions and is worth 200 points. The test consists of multiple choice questions worth 4 points each and open ended questions worth 20 points each. How many of each type of question are there
Answer provided by our tutors
Let
x = the number of multiple choice questions
y = the number of open ended questions
x + y = 38 the total number of questions
4*x + 20*y = 200
By solving the system of eqautions
x + y = 38
4*x + 20*y = 200
we find
x = 35
y = 3
There are 35 multiple choice questions and 3 open ended questions.
