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 determine the lower unit price, you need to calculate the cost per ounce for each size of ice cream:

For the 48-ounce container, the cost is $4.50. So, the cost per ounce is $4.50 / 48 ounces = $0.09375 per ounce.

For the 128-ounce container, the cost is $7. So, the cost per ounce is $7 / 128 ounces = $0.0546875 per ounce.

For the 64-ounce container, the cost is $3. So, the cost per ounce is $3 / 64 ounces = $0.046875 per ounce.

The 64-ounce container has the lower unit price at approximately $0.046875 per ounce.
