Colin is painting figurines. He spends 20 minutes painting each figurine. After painting for 60 minutes, he still has 9 more figurines left to paint. The number fff of figurines left to paint is a function of ttt, the amount of time in minutes Colin spends painting.

Step-by-step explanation:

Given

Required

Determine the function

From the question, we have:

This is represented as:

or

If he spends 20 minutes on 1 figurine;

Multiply both sides by 3

This means that, he spends 60 minutes on 3

plus he still has 9 left

So, the initial figurines is:

or

So, we have:

and

Calculate the slope (m)

The equation is then calculated as;

To solve for c, we have:

So, we have:

Add 3 toboth sides

Hence, the equation is:

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
