ESTIMATION PROBLEM

More of an art than a science. You must find what works for your brain.

Do EASY things first.

2.17 * 10 = 21.70 - That took almost no time and eliminated two possible answers.

It's okay to need to have initial posts approved. Don't try to circumvent the system.

Wait! I am SURE this answer choice should have been instead:

"c. between 10 and 11" instead.

Just look at the pattern of the choices. The "19" must have
been a typo ** for the desired "10."


d more than 11.

** The "9" key (as in "19" here), and "0" key (as in "10" here),
are right next to each other.
