Questions: 17. A 128-fluid-ounce container of laundry detergent sells for 7.99. A 36-fluid-ounce container sells for 3.59. About how much can be saved per ounce by buying the larger container? A 0.10 B. 0.07 C. 0.05 D. 0.04 18. There are 100 centimeters in 1 meter. How many centimeters are there in 55 meters? A 55,000 B. 5,500 C. 550 D. 55

Solution Steps

• The larger container is 128 fluid ounces and costs \$7.99.
• Calculate the cost per ounce: \[ \text{Cost per ounce for larger container} = \frac{7.99}{128} \]

• The smaller container is 36 fluid ounces and costs \$3.59.
• Calculate the cost per ounce: \[ \text{Cost per ounce for smaller container} = \frac{3.59}{36} \]

• Subtract the cost per ounce of the larger container from the cost per ounce of the smaller container to find the savings: \[ \text{Savings per ounce} = \left(\frac{3.59}{36}\right) - \left(\frac{7.99}{128}\right) \]

• There are 100 centimeters in 1 meter.
• To find the number of centimeters in 55 meters, multiply: \[ 55 \times 100 \]
