Answer: $14.40
Step-by-step explanation:
To calculate the tip, we can multiply the bill amount by the tip percentage (in decimal form). Then, we add the tip amount to the bill to get the total amount to pay.
Given that the bill is $12 and the tip is 20%:
1. Calculate the tip amount
Tip = 12 · 0.20 = $2.40
2. Add the tip to the bill
Total = 12 (bill) + 2.40 (tip)
Total = 14.40
