Answer:
Step-by-step explanation:
<u>Plan A remains with $450 stable charge and Plan B is:</u>
- 200 + 30x, with x being the number of physical training sessions
<u>In order Plan B to be cheaper we set an inequality:</u>
- 200 + 30x < 450
- 30x < 250
- x < 250/30
- x = 8.33 < 9
Answer:
a. E = 50 H b. 950 dollars
Step-by-step explanation:
a. Since Rachel tutors English for 50 dollars for each hours, her rate is 50 dollar per hour. If she tutors for time, H hours, Her earning E = rate × time = 50 × H
E = 50H.
b. If Rachel's earnings after tutoring for 19 hours is gotten by substituting H = 19 into the equation for the earnings, E.
So, E = 50H
E = 50 × 19
E = 950 dollars.
So, Rachel's earnings after 19 hours is 950 dollars.
