While dining out, Chad spent $25.00. If the bill totaled $21.00 before the tip was added, approximately what percent tip did Chad leave?

Detailed Explanation

Calculate the tip amount: Subtract the bill amount before the tip from the total amount he paid, including the tip.

Tip amount = 25.00 (total paid) - 21.00 (bill before tip) = 4.00

Divide the tip amount by the bill amount before the tip and multiply by 100% to express it as a percentage:

Tip percentage = (4.00 tip amount) ÷ (21.00 bill) × 100% ≈ 19%

Therefore, Chad left an approximate tip of 19%.

Tip amount = 25.00 (total paid) - 21.00 (bill before tip) = 4.00

Divide the tip amount by the bill amount before the tip and multiply by 100% to express it as a percentage:

Tip percentage = (4.00 tip amount) ÷ (21.00 bill) × 100% ≈ 19%

Therefore, Chad left an approximate tip of 19%.
