Answer:
A(t) = -7.5t +50
Step-by-step explanation:
The computation is shown below:
Here we use the two point form i.e. presented below
(y - y_1) = (y_2 - y_1) ÷ (x_2 - x_1)
where,
Y = painted area
x = elapsed time
x_1 = 0
y_1 = 50
x_2 = 2
y_2 = 35
Now place the values to the above formula
So,
The area to be painted should be
A(t) = -7.5t +50
Answer: x=6.8
