x + y = 15 and 5x + 10y = 100 are the system of equations that represent this situation
<em><u>Solution:</u></em>
Let "x" be the number of multiple choice questions
Let "y" be the number of short answer questions
Worth of 1 multiple choice questions = 5 points
Worth of 1 short answer question = 10 points
<em><u>Ms. Lee wrote a test with 15 multiple choice short answer questions</u></em>
Therefore,
number of multiple choice questions + number of short answer questions = 15
x + y = 15 -------- eqn 1
<em><u>The maximum number of points possible on the test is 100</u></em>
Therefore, we frame a equation as:
number of multiple choice questions x Worth of 1 multiple choice questions + number of short answer questions x Worth of 1 short answer question = 100
5x + 10y = 100 ------- eqn 2
Thus eqn 1 and eqn 2 are the system of equations that represent this situation
Answer:
The total number of units produced is 6 .
Step-by-step explanation:
Given as :
The earning of worker at the factory = $ 12 per hour + $ 2.50 each unit per hour
The total earning of worker per hour = $ 27
Let The total number of unit produced = x
According to question
The wage worker earn per hour + earning × per unit produced that hour = Total earning of worker per hour
Or, $ 12 per hour + $ 2.50 each unit per hour × x = $ 27
Or, $ 2.50 each unit per hour × x = $ 27 - $ 12
Or, $ 2.50 each unit per hour × x = $ 15
∴ x =
Or, x = 6
Hence The total number of units produced is 6 . Answer
