Answer:
Step-by-step explanation: By using linear inequation, it can be calculated that-
After 50 hours, Plan B be more profitable than Plan A for the painter
What is linear inequation?
Inequation shows the comparision between two algebraic expressions by connecting the two algebraic expressions by >, <, ≥, ≤
A one degree inequation is known as linear inequation.
Here, a linear inequation needs to be solved
Let after t hours, Plan B be more profitable than Plan A for the painter
For plan A
A painter Charges $500 plus $45 per hour
Cost after t hours = $(500 + 45t)
For plan B
A painter Charges $55 per hour
Cost after t hours = $55t
By the problem,
55t > 500 + 45t
55t - 45t > 500
10t > 500
t >
t > 50
After 50 hours, Plan B be more profitable than Plan A for the painter
