Question

Estimate a 15% tip on a dinner bill of $32.47 by first rounding the bill amount to the nearest ten dollars.

Estimated tip: $

Answer 1

$4.50

Explanation:

First round to the nearest $10, as instructed. This will give us a bill amount of $30 once rounded. We do not round up as $32.47 is closer to $30 than 40$.

To get 15% of $30 we can simply multiply $30 by 0.15, which is the decimal equivalent of 15%.

This leaves us with an answer of $4.50.
