PLEASE HELP IT IS EASY!!!!!!!!!!!!!! I HAVE AN EXAM!!!!!!!!!!!!!!! A student took 75 minutes to answer a combination of 30 multiple-choice and extended-response questions. She took 2 minutes to answer each multiple-choice question and 5 minutes to answer each extended-response question.

Determine which two equations best represent the situation given that R represents the number of extended-response questions and M represents the number of multiple-choice questions.
Determine the number for each type of question on the test.

Answer 1

M+R=30

2M+5R=75

R=5

M=25

Explanation:

-2(M+R=30)

2M+5R=75

-2M-2R=-60

2M+5R=75

__________

3R=15

R=5

2M+5(5)=75

2M+25=75

2M=50

M=25
