Final answer:
To find the cost of 30 packages of licorice when 5 packages cost $10, we calculate the cost of one package and then multiply by 30 to get a total of $60.
Step-by-step explanation:
If 5 packages of licorice cost $10, we need to calculate the cost of 30 packages. First, we find out how much one package costs by dividing the cost of 5 packages by 5:
Cost of one package = $10 ÷ 5 = $2
Now that we know the cost of one package, we multiply that by 30 to find the total cost for 30 packages:
Total cost for 30 packages = 30 × $2 = $60
Therefore, the correct answer is C. $60.
