Question

Estimate a 15% tip on a dinner bill of 79.45 by first rounding the bill amount to the nearest ten dollars.

Answer 1

Answer: 12$

Step-by-step explanation:

We need to round 79.45 to the nearest 10 dollars, which is 80.

We can then get 15% of it easily since its a whole number by adding 10% (8) and 5% (4) to get an estimate of around 12 dollars.
