Explanation:

Problem 1 (Sarah's Ribbon)

Step 1: Convert feet to inches

Sarah has 7 feet of ribbon. Since 1 foot = 12 inches, we calculate the total inches: \( 7 \times 12 = 84 \) inches.

Step 2: Compare with needed length

She needs 80 inches. Since \( 84 > 80 \), she has enough.

Step 1: Convert pounds to ounces

Marcie has 6 pounds of dog food. Since 1 pound = 16 ounces, we calculate: \( 6 \times 16 = 96 \) ounces.

Step 2: Compare with weekly need

She needs 98 ounces per week. Since \( 96 < 98 \), she does not have enough.

Step 1: Convert meters to centimeters

Tavon is 1.6 meters tall. Since 1 meter = 100 centimeters, we calculate: \( 1.6 \times 100 = 160 \) centimeters.

Answer:

Sarah has 84 inches of ribbon. Yes, she has enough because 84 inches > 80 inches.
