Final answer:
To calculate the unit rate for $110 for 14 square feet, divide the total cost by the number of square feet to find the cost per square foot. The calculation is $110 ÷ 14, which equals approximately $7.86, making (A) the correct answer.
Step-by-step explanation:
The student has asked what the unit rate is for $110 for 14 square feet. To find the unit rate, you would divide the total cost by the number of units (in this case, square feet). So, you would calculate $110 ÷ 14ft2 to find the cost per one square foot. Let's do the math:
$110 ÷ 14ft2 = $7.8571...
When rounding to the nearest hundredths place (cents), it gives us approximately $7.86. Therefore, option (A) $7.86 is the correct unit rate.
