• 13. Discount Store Savings on Water

At a supermarket, a 24-pack of 16.9-fluid-ounce bottles of water costs \$4.99.

1. At a discount store, a 35-pack of 16.9-fluid-ounce bottles of water costs \$4.49. Suppose you buy all your bottled water at the discount store instead of at the supermarket. How much will you save per year?

2. Your tap water rate is \$2.62 per 1000 gallons of water. Suppose you use tap water instead of buying bottled water at the supermarket. How much will you save per year? (See Example 5 and Example 6.)

• Worked-Out Solution
1. Begin by calculating the annual cost from each source.

You would save \$17.56 per year by buying your bottled water at a discount store.

2. At \$2.62 for 1000 gallons, tap water is close to being free.

You would save \$45.75 per year by using tap water instead of buying bottled water at a supermarket

• 14. Savings on Homemade Coffee Creamer

You use 0.5 fluid ounce of coffee creamer with each 6-fluid-ounce "cup" of coffee. The creamer that you use costs \$2.19 for 16 fluid ounces. You can make homemade coffee creamer using the recipe shown. (See Example 5 and Example 6.)

• Estimate how much you could save annually by making your own creamer.
• The vanilla extract is optional. Estimate how much you could save annually by making your own creamer without the vanilla instead of buying the creamer at the store.
