Final answer:
To find the better buy between Brand C and Brand D chicken noodle soup, one must calculate and compare their unit prices. Brand C costs approximately $0.073 per ounce, while Brand D costs approximately $0.088 per ounce.
Step-by-step explanation:
The question asks to compare the unit prices of two brands of chicken noodle soup to determine the better buy. The unit price is calculated by dividing the price of the product by the quantity (ounces in this case). To solve this, we need to calculate the unit price for both Brand C and Brand D.
For Brand C, the unit price is calculated as $1.89 for 26 ounces. So:
Unit Price for Brand C = $1.89 / 26 ounces = $0.0727 per ounce.
For Brand D, the unit price is calculated as $0.95 for 10.75 ounces. So:
Unit Price for Brand D = $0.95 / 10.75 ounces = $0.0884 per ounce.
Comparing both unit prices, Brand C's unit price of approximately $0.073 per ounce is less than Brand D's unit price of approximately $0.088 per ounce. Therefore, Brand C is the better buy.
