What is the price per ounce of spices? $

Answer 1

To find the price per ounce of spices, we can use the information from the table.

First, we note the total cost at 0 ounces, which is $5.00. This represents the cost of the jar. For every additional ounce of spices, there is an additional cost.

Next, let's look at the data points provided in the table:

• At 0 ounces, the total cost is $5.00.
• At 2 ounces, the total cost is $14.00.
• At 4 ounces, the total cost is $23.00.
• At 10 ounces, the total cost is $50.00.

To find the cost of spices per ounce, we can look at the difference in total cost as ounces increase:

1. From 0 to 2 ounces: $$\text{Cost for 2 ounces}=\$14.00-\$5.00=\$9.00$$ This means that 2 ounces of spices cost $9.00, so the price per ounce is: $$\text{Price per ounce}=\frac{\$9.00}{2}=\$4.50$$

2. We can verify this with the other data points as well:

   • From 2 ounces to 4 ounces: $$\text{Cost for 2 more ounces}=\$23.00-\$14.00=\$9.00$$
   • From 4 ounces to 10 ounces (6 ounces): $$\text{Cost for 6 ounces}=\$50.00-\$23.00=\$27.00$$ Cost per ounce for 6 ounces: $$\text{Price per ounce}=\frac{\$27.00}{6}=\$4.50$$

Thus, the price per ounce of spices is $4.50.
