2. scott is buying kale chips for his lunches. he can buy a pack of six $\frac{1}{2}$ -ounce bags of kale chips for $9.00, or he can buy one 5 -ounce bag of kale chips for $12.50. which option costs less per ounce of kale chips? explain.

Answer

Explanation:

Step1: Calculate total ounces for first - option

Each bag is $\frac{1}{2}$ ounce and there are 6 bags. So total ounces $=6\times\frac{1}{2}=3$ ounces.

Step2: Calculate cost per ounce for first - option

Cost is $9$ dollars for 3 ounces. Cost per ounce $=\frac{9}{3}=3$ dollars per ounce.

Step3: Calculate cost per ounce for second - option

Cost is $12.5$ dollars for 5 ounces. Cost per ounce $=\frac{12.5}{5}=2.5$ dollars per ounce.

Step4: Compare costs per ounce

Since $2.5<3$, the second option costs less per ounce.

Answer:

The one 5 - ounce bag for $12.50$ costs less per ounce.
