Question

a meal at a restaurant originally costs $25. you leave an extra 20% tip. how much will you pay? 25 + 20 = $45 25 x.80 = $20 25 x 1.20 = $30 25 + 0.2 = $25.20

Explanation:

Step1: Calculate the tip amount

The tip is 20% of the meal cost. 20% as a decimal is 0.2. The tip amount is $25\times0.2 = 5$.

Step2: Calculate the total amount paid

The total amount paid is the meal cost plus the tip, so $25 + 5=30$. Another way is to note that the total amount is 120% of the meal - cost (100% for the meal and 20% for the tip). 120% as a decimal is 1.2, and $25\times1.2 = 30$.

Answer:

$25\times1.20 = \$30$ is the correct answer.
