If Sonia wraps 7 gifts per hour, then how many gifts does she wrap in 20 hours?

00:00 How many gifts does Sarah wrap in 20 hours?

00:03 Given: number of gifts per hour, number of hours

00:08 We'll use long multiplication to calculate

00:12 We'll solve each multiplication separately and then substitute in the long multiplication

00:23 And this is the solution to the question

To determine how many gifts Sonia wraps in 20 hours when she wraps 7 gifts per hour, we will calculate as follows:

Step 1: Identify the rate: $7$ gifts per hour.
Step 2: Identify the time duration: $20$ hours.
Step 3: Use the formula: Total number of gifts = (Number of gifts per hour) × (Number of hours).
Step 4: Perform the calculation: $7 \text{ gifts/hour} \times 20 \text{ hours} = 140 \text{ gifts}$ .

Therefore, Sonia wraps $140$ gifts in 20 hours.

Comparing this result with the provided choices, we determine that the correct choice is: $140$ .

$140$
