Question

Hector charges $12 an hour for his tutoring services. If he tutors 26 hours in one week, how much money has he made?​

Answer 1

312

Explanation:

For this problem, we don't need to actually calculate. Use common sense.

Is 26*12 greater than 14? Yes

Is 26*12 greater than 38? Yes

Is 26*12 greater than 312? We haven't calculated so there is no exact answer.

Is 26*12 greater than 96? Yes

We have eliminated choices 14, 38, and 96. We are left with the answer, 312. Though we didn't do the calculation, the common sense (when applicable) method is more efficient. The answer is 312.

You can always check.

26*12 = 26(10+2) = 260 + 52 = 312

Hope this helps :)

Have a nice day!
