The total amount Serena earns is the sum of her regular wage and the tips. The amount she earns from the wage is equal to 9h. This total should be more than or equal to $110. This is mathematically expressed as,
9h + 15 ≥ 110
The initial fee of $50 is essentially the y intercept because this is the value when x = 0 (x is the number of labor-hours). So b = 50.
The slope is m = 30 because each increase of 1 hour leads to the cost bumping up by 30 dollars. In other words, slope = rise/run = (change in cost)/(change in hours) = 30/1
So we plug m = 30 and b = 50 into the y = mx+b formula to get y = 30x+50
Replace y with f(x) to get f(x) = 30x+50
The linear function for the cost is f(x) = 30x+50
Note: Some books may use other letters (instead of x and f(x)), but the idea is still the same
Once you know the cost function, you replace x with 4.5 to find the amount it will cost to have a painter work for 4.5 hours.
f(x) = 30x+50
f(4.5) = 30*4.5+50
f(4.5) = 135+50
f(4.5) = 185
It will cost 185 dollars to have the painter work for 4.5 hours
Answer:
(F). People may have a career following their passion, but have a low income or a long commute.
(A). A working spouse could affect all three variables. (C).People might be very satisfied with their career as long as the income is high.
(E). One-way commute times may be long because affordable housing is distant from the job.
Step-by-step explanation:
a. People may have a career following their passion, but have a low income or a long commute.
sometimes people can get jobs based on their passion but might still have low income and a long commute.
b. A working spouse could affect all three variables.
Yea a working spouse considers the income rate, job satisfaction and commute time involved in a job because it can affect their daily lives.
c. People might be very satisfied with their career as long as the income is high.
Most people are more satisfied with their career when the income rate is high.
d. One-way commute times may be long because affordable housing is distant from the job.
Income rate affects the choice of accommodation and housing.
