Question

Estimate a 20% tip on a dinner bill of $179.62 by first rounding the bill amount to the nearest ten dollars.​

Answer 1

Answer:

$216

Step-by-step explanation:

Round the bill to $180, and multiply by 0.2. An easy way to do this is to multiply 180 by 2. We get 360, and divide that by 10. This gives us our 20% tip at $36. Add this to $180 to get $216.
