We know that
[area of the painting]=13 in* 17 in-----> 221 in²
if a<span>n artist painting at
$0.30 per --------------> 1 in</span>²
x$--------------> 221 in²
X=221*0.30------> x=$66.30
the answer is
$66.30

Slope of a function is defined as the rate of change of a function. It determine the unit price of values or amount traveled in unit time.
<h3>Slope of a function</h3>
Slope of a function is defined as the rate of change of a function. It determine the unit price of values or amount traveled in unit time.
The formula for expressing the slope of a function is given as;
f'(x) = f(b)-f(a)/b-a
a and b are the intervals
The slope can also be expressed as a function of its coordinate (x, y)
Slope = y2-y1/x2-x1
