Answer:
$317.475 is the selling price for the painting

You are given the cost per square inch is $4.15, therefore multiply
76.5 ×4.15 = $317.475 or if you need to round to whole number $317.
9 4/5 as a decimal is 9.8
t^6
when dividing exponents, you subtract (refer to exponent rule)
t^12 - t^6 = t^6
5.58
