Q. Hailey paid $13\$13 for 1371\dfrac{3}{7} kg\text{kg} of sliced salami. What was the cost per kilogram of salami
  1. Convert to Improper Fraction: Convert the mixed number 1371 \frac{3}{7} to an improper fraction to make the calculation easier.137=(7×1+3)7=1071 \frac{3}{7} = \frac{(7\times1 + 3)}{7} = \frac{10}{7}
  2. Calculate Cost per Kilogram: Calculate the cost per kilogram by dividing the total cost by the weight of the salami in kilograms.\newlineCost per kilogram = Total cost / Weight in kilograms\newlineCost per kilogram = $13/(107)\$13 / (\frac{10}{7}) kg
  3. Perform Division: Perform the division by multiplying $13\$13 by the reciprocal of 107\frac{10}{7}.\newlineCost per kilogram = $13×(710)\$13 \times \left(\frac{7}{10}\right)\newlineCost per kilogram = $9110\$\frac{91}{10}\newlineCost per kilogram = $9.10\$9.10
