Question

At the grocery store one brand of ice cream cost $4.50 for 48 oz The same brand cost $7 for $120 oz or $3 for 64 oz which size has the lower unit price A 128 ounces B 64 ounces C They cost the same per ounce D 48 ounces

Answer 1

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

1. **48 oz for $4.50:**
\[
\text{Unit price} = \frac{4.50}{48} = 0.09375 \text{ (or about 9.38 cents per ounce)}
\]

2. **120 oz for $7:**
\[
\text{Unit price} = \frac{7}{120} \approx 0.05833 \text{ (or about 5.83 cents per ounce)}
\]

3. **64 oz for $3:**
\[
\text{Unit price} = \frac{3}{64} = 0.046875 \text{ (or about 4.69 cents per ounce)}
\]

Now we compare the unit prices:

- 48 oz: ≈ 9.38 cents per ounce
- 120 oz: ≈ 5.83 cents per ounce
- 64 oz: ≈ 4.69 cents per ounce

The lowest unit price is for the 64 oz option.

Thus, the answer is **B 64 ounces**.
