Answer:
1 hour and 30 minutes (1.5 hours)
Step-by-step explanation:
$25 per hour is our slope and $25 call fee is our y-intercept.
We can write a linear function in slope-intercept form like this:
Where m is your slope, y is the total cost, x is the hours worked b is your y-intercept. Therefore using the information above we obtain:
Since the bill comes out to be $62.50 that means that y=62.50 by substituting that value we have to solve for x since x is the amount of hours worked we obtain:
Since x = 1.5 this means that the plumber worked for one and a half hours or 1 hour and 30 minutes.

Answer:
- 320 +0.05s ≥ 600
- sales ≥ $5600
Step-by-step explanation:
For sales of 's', Alan's earnings will be ...
320 +0.05s
He wants that to be at least 600, so the inequality is ...
320 +0.05s ≥ 600
__
Its solution is found by subtracting 320 and dividing by 0.05.
0.05s ≥ 280
s ≥ 5600
Alan's weekly sales must be at least $5600 for his earnings to cover his expenses.
