Answer:
They would be the same after 10 days.
Step-by-step explanation:
In order to find this, we must first create two equations. Let x be the number of days that are rented. We'll first create an equation for the first company. Since it costs $8 per day, let 8 be the coefficient of x and 20 be the constant.
y = 8x + 20
Now, do the same with the second company.
y = 5x + 50
Now that we have these, set them equal to each other to get the answer.
8x + 20 = 5x + 50
3x + 20 = 50
3x = 30
x = 10
