Answer 1

Answer: $14.55

Step-by-step explanation: What you do is

$0.75*4= $3

then $5.99*3=$17.97

12*$1.89=$22.68

Now you add it all and get $43.65.

Since its asking per painting you're going to find the unit rate by dividing. 43.65/3

So your answers would be 14.55.

Answer 2

Answer:

Average cost of the painting = $14.55

Step-by-step explanation:

According to the question:

• Number of brushes used = $4$

       Total cost of brushes = $(4\times 0.75) =\ 3$

Note:Total cost of any item = Product of number of items with                   its unit price.

• Number of canvases = $3$

       Total cost of canvases = $(3\times 5.99)=\ 17.97$

• Number of tubes used = $12$

       Total cost of tubes = $(12\times 1.89)=\ 22.68$

• Number of paintings = $3$

We have to find the average cost of painting.

Let the average cost be 'x' .

So,

⇒ $x=\frac{Total\ expenditure}{Number\ of\ paintings}$

⇒ $x=\frac{3+17.97+22.68}{3}$

⇒ $x=\ 14.55$

Average cost of the painting = $14.55
