Question
You earn $18 for every hour you work. The equation that represents this function is,
- y=(18/2)x + 0
- y = 18x
- y = 2x + 18
- y = 18x + 2
Hint:
Total Earnings = Number of hours worked * Rate per hour.
The correct answer is: y = 18x
GIVEN-
Rate of earnings = $ 18 per hour.
TO FIND-
Equation for the given situation to determine the total earnings.
SOLUTION-
Let the total earnings be y & number of hours worked be x.
We know that-
Total Earnings = Number of hours worked * Rate per hour
∴ y = x * $ 18 …....................................................................... (From given information)
∴ y = 18 x
FINAL ANSWER-
Option 'b' i.e. 'y = 18x' is the correct answer to the given question.
