____ [38]

Answer: Total molding cost is $197.20.

Step-by-step explanation:

Since we have given that

Length of oil painting frame = 22 inch

Width of oil painting frame = 30 inch

Width for molding = 4 inches

So, Length after molding would be

4+22+4 = 30 inches

Width after molding would be

4+30+4 = 38 inches

So, Perimeter of molding would be

$2(L+B)\\\\=2(30+38)\\\\=2\times 68\\\\=136\ inches$

Cost per inch = $1.45

So, Total molding cost would be

$1.45\times 136\\\\=\$197.20$

Hence, Total molding cost is $197.20.
