Complete Question

On a two week job, a repairman works a total of 70 hours. He charges $75 plus $40 per hour. An equation shows the relationship where x is the number of hours and y is the total fee. Write the equation. What is the slope and y-intercept?

a)Write the equation.

y = 40x + 75

b) What is the slope and y-intercept?

The slope = 40

y - Intercept = 75

Step-by-step explanation:

On a two week job a repairman works a total of 70 hours. He charges 75$ plus 40$ per hour.

The equation shows this realationship where x is the number of hours and y is the total fee is given using the equation of a straight line which is given as:

y = mx + c

Where m = Slope

c = y intercept

Applying this equation to our question , we have:

y= 40x + 75

The slope = m = 40

y-intercept = c = 75

75 y intercept.

Step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
