Question
Kaya rented a limousine for prom. There was a one-time charge of $100, plus an hourly rate of $45. Her total cost for the night was $347.50. Find the total hours Kaya rent the limo for.
- 347.50 = 100x + 45
- 347.50 = 45x + 100
- 347.50 - 100 = 45x
- 347.50 + 45x = 100
Hint:
In this question, we have to write the equation for this question. Now , Kaya rented a limousine for prom , one time charge is $100, plus hourly rate of $45. Total cost is $347.50. Plus means addition and one time charge is fixed number means constant but hourly rate is varies on each hour so it is variable.
The correct answer is: 347.50 = 45x + 100
Here we have to write the equation of this question.
Firstly , we have given statement is ,
One time charge is $100 plus hourly rate of $45 is equal to $ 347.50.
When plus is given it is always addition .
Whenever increased, more than, plus, added, are used we always uses the addition.
And here one time charge is fixed number means constant but hourly rate is varies on each hour so it is variable.
So we can write the equation of total cost is,
100 + 45x = 347.50
So the total hours is after solving is, x = 5.5h
Therefore, the correct answer is 347.50 = 45x + 100
In this question we have to find the total time and also write the equation. IF plus was in the question that means addition . You have to just find which is constant and which is variable and then write the equation according them.
