Final answer:
The correct equation is (A) 25 + 5x = 30 + 4x. In this equation, 'x' represents the number of additional windows. By setting the prices of both companies equal to each other, we can find the number of blinds needed for the prices to be equal.
Step-by-step explanation:
The correct equation to determine how many blinds would need to be installed for the price to be equal is (A) 25 + 5x = 30 + 4x.
In this equation, 'x' represents the number of additional windows.
By setting the prices of both companies equal to each other, we can find the number of blinds needed for the prices to be equal.
