Answer:
The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.
Step-by-step explanation:
☆Let's solve using proportion.
☆One box:
![\frac{16 \: oz.}{3.50 \: dollars} = \frac{1 \: oz.}{x} \\ \\ \frac{3.50}{16} = \frac{16x}{16 } \\ \\ 0.22 = x](https://tex.z-dn.net/?f=%20%5Cfrac%7B16%20%5C%3A%20oz.%7D%7B3.50%20%5C%3A%20dollars%7D%20%20%3D%20%20%5Cfrac%7B1%20%5C%3A%20oz.%7D%7Bx%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B3.50%7D%7B16%7D%20%20%3D%20%20%5Cfrac%7B16x%7D%7B16%20%7D%20%20%5C%5C%20%20%5C%5C%200.22%20%3D%20x)
☆Another box:
![\frac{24 \: oz.}{3.89 \: dollars} = \frac{1 \: oz.}{x } \\ \\ \frac{3.89}{24} = \frac{24x}{24} \\ \\ x = 0.16](https://tex.z-dn.net/?f=%20%5Cfrac%7B24%20%5C%3A%20oz.%7D%7B3.89%20%5C%3A%20dollars%7D%20%20%20%3D%20%5Cfrac%7B1%20%5C%3A%20oz.%7D%7Bx%20%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B3.89%7D%7B24%7D%20%20%3D%20%20%5Cfrac%7B24x%7D%7B24%7D%20%20%5C%5C%20%5C%5C%20x%20%3D%200.16)
☆All we need to do is subtract: ![0.22 - 0.16 = 0.06](https://tex.z-dn.net/?f=0.22%20-%200.16%20%3D%200.06)
☆The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.
