Question

Find unit rate or cost of 1 lb of cheese from table below.
6lb-$9
5lb-$7.50
4lb-$6
3lb-4.50

Answer 1

To find the unit rate or cost of 1 pound of cheese, you can divide the total cost by the number of pounds for each option. Here are the calculations:

1. For 6 lb at $9:
\[
\text{Cost per lb} = \frac{9}{6} = 1.50 \text{ dollars per lb}
\]

2. For 5 lb at $7.50:
\[
\text{Cost per lb} = \frac{7.50}{5} = 1.50 \text{ dollars per lb}
\]

3. For 4 lb at $6:
\[
\text{Cost per lb} = \frac{6}{4} = 1.50 \text{ dollars per lb}
\]

4. For 3 lb at $4.50:
\[
\text{Cost per lb} = \frac{4.50}{3} = 1.50 \text{ dollars per lb}
\]

In each case, the unit rate or cost of 1 lb of cheese is $1.50.
