Which box gives you more cereal for your money?
First solve for the volume of each box of cereal. FORMULA SHEET.
Second, find the unit price for each box. PRICE/cubic inch. Do not round. Write out all of the decimals.
Third, compare the prices. Which box of cereal is cheaper per cubic inch?
Volume of Box A: 16in x 4in x 10in = 640 cubic inches
Volume of Box B: 10in x 8in x 2in = 160 cubic inches
Unit price of Box A: $6 / 640 cubic inches = $0.009375 / cubic inch
Unit price of Box B: $3 / 160 cubic inches = $0.01875 / cubic inch
Comparing the prices:
Box A has a cheaper unit price per cubic inch, so it gives you more cereal for your money.
can you explain the unit price thingy? I don't understand it.
Sure! The unit price is the cost per unit of measurement, in this case, the cost per cubic inch. To find the unit price, you divide the total price by the total quantity in the same units.
In this case, for Box A, the total price is $6 and the total quantity (volume) is 640 cubic inches. So, to find the unit price per cubic inch, you divide $6 by 640 cubic inches.
Similarly, for Box B, the total price is $3 and the total quantity (volume) is 160 cubic inches. To find the unit price per cubic inch for Box B, you divide $3 by 160 cubic inches.
Comparing the unit prices helps you determine which box of cereal gives you more cereal for your money by looking at the cost per cubic inch. In this case, Box A has a lower unit price per cubic inch compared to Box B, making it the better value for your money in terms of cereal quantity.
I hope this explanation helps clarify the concept of unit price for you! Let me know if you have any other questions.
