Question

At the grocery store, one brand of ice cream costs $4.50 for 48 ounces. The same brand costs $7 for 128 ounces or $3 for 64 ounces. Which size has the lower unit price?

Answer 1

To find the unit price, we divide the cost by the number of ounces.

For the size costing $4.50 for 48 ounces, the unit price is $4.50/48 = $<<4.50/48=0.094>>0.094 per ounce.

For the size costing $7 for 128 ounces, the unit price is $7/128 = $<<7/128=0.055>>0.055 per ounce.

For the size costing $3 for 64 ounces, the unit price is $3/64 = $<<3/64=0.047>>0.047 per ounce.

Therefore, the size with the lower unit price is the one that costs $3 for 64 ounces. Answer: \boxed{64}.

Answer 2

To determine which size has the lower unit price, we need to find the price per ounce for each size.

First, let's calculate the price per ounce for the 48-ounce container:
Price per ounce = total price / total ounces
Price per ounce = $4.50 / 48 ounces
Price per ounce = $0.09375 per ounce

Now, let's calculate the price per ounce for the 128-ounce container:
Price per ounce = total price / total ounces
Price per ounce = $7 / 128 ounces
Price per ounce = $0.0546875 per ounce

Lastly, let's calculate the price per ounce for the 64-ounce container:
Price per ounce = total price / total ounces
Price per ounce = $3 / 64 ounces
Price per ounce = $0.046875 per ounce

Comparing the three prices per ounce, we can see that the 64-ounce container has the lowest unit price at $0.046875 per ounce.

Answer 3

To find out which size has the lower unit price, we need to compare the unit prices of each size. Unit price is the price per ounce or unit of a particular item.

For the first size, the ice cream costs $4.50 for 48 ounces. To find the unit price, we need to divide the total price by the number of ounces:

Unit price = Total price / Number of ounces
Unit price = $4.50 / 48 oz
Unit price = $0.09375/oz

For the second size, the ice cream costs $7 for 128 ounces:

Unit price = Total price / Number of ounces
Unit price = $7 / 128 oz
Unit price = $0.0546875/oz

For the third size, the ice cream costs $3 for 64 ounces:

Unit price = Total price / Number of ounces
Unit price = $3 / 64 oz
Unit price = $0.046875/oz

Comparing the unit prices:

First size: $0.09375/oz
Second size: $0.0546875/oz
Third size: $0.046875/oz

Comparing the unit prices, we can see that the third size, which costs $3 for 64 ounces, has the lowest unit price of $0.046875/oz. Therefore, the third size has the lower unit price among the three sizes.
