UpStudy AI · Accepted Answer

To calculate the expression:

$$
3\, \mathrm{lb} \times \frac{\$1.29}{\mathrm{lb}}
$$

**Step 1: Multiply the Numerical Values**

$$
3 \times 1.29 = 3.87
$$

**Step 2: Simplify the Units**

$$
\mathrm{lb} \times \frac{\$}{\mathrm{lb}} = \$
$$

The units of pounds (lb) cancel out, leaving you with dollars ($).

**Final Result:**

$$
3\, \mathrm{lb} \times \frac{\$1.29}{\mathrm{lb}} = \$3.87
$$

**Interpretation:**

If you're purchasing 3 pounds of an item priced at \$1.29 per pound, the total cost would be **\$3.87**.
The total cost is \$3.87.
