Q. A 99-foot roll of plastic wrap costs $5.40\$5.40. What is the price per inch? \newline $\$ _____
  1. Question Prompt: Question prompt: What's the price per inch for a 99-foot roll of plastic wrap that costs $5.40\$5.40?
  2. Calculate Inches: First, let's figure out how many inches are in 99 feet. Since 11 foot is 1212 inches, we do 9×129 \times 12.\newline9×12=1089 \times 12 = 108 inches.
  3. Calculate Cost Per Inch: Now, we got the total cost, which is \$\(5\).\(40\), and we need to divide that by the total number of inches to get the cost per inch.\(\newline\)So, \$\(5\).\(40\) divided by \(108\) inches.\(\newline\)\(\$5.40 / 108 = \$0.05\) per inch.
