Question

What is a 10% tip on a bill of $42.87? (Round to the nearest cent.)

Answer 1

Answer:

$4.29

Step-by-step explanation:

An easy way to do this is to move the decimal point to the left one space.

So 42.87 would become 4.287

But since we are talking about currency, we only want two numbers to the right of the decimal point: 4.28.

And since we are rounding to the nearest cent, the 7 on the end means we round up by 1, making the final answer 4.29!
