Question

Javier was shopping at the grocery store for some olives. He needed a lot of olives, so he grabbed the large jar off the shelf. Then he noticed the price. The large jar contained 20 oz. of olives and it cost $3.99. He looked at the small jar of olives. It contained 10 oz. of olives and cost $1.49. Javier put the large jar back and purchased two small jars of olives.

Answer 1

Javier analyzed the unit prices of two sizes of olive jars and found that buying two small jars was more cost-effective than one large jar, saving him $1.01 on a total of 20 oz. of olives.

Step-by-step explanation:

The question revolves around comparing the unit prices of two different sizes of olive jars to determine which option offers a better value. Javier finds a large jar of olives at 20 oz. for $3.99 and a small jar at 10 oz. for $1.49. To compare the unit price of each, we divide the total cost by the quantity of olives in each jar.

• Large jar unit price: $3.99 / 20 oz. = $0.1995 per ounce
• Small jar unit price: $1.49 / 10 oz. = $0.149 per ounce

Javier realized that buying two small jars, which totals 20 oz., would cost $2.98 (2 x $1.49), saving him $1.01 compared to the large jar. Thus, purchasing two small jars is the more cost-effective choice. This is an application of unit price comparison in a real-world scenario.
