The Brown Office Rental Company has purchased a new computer for the secretary to use for customer requests. She can type 70 words per minute, on the average. If she types 4 to 5 hours per day, she will average how many words, w, per day?

F 16,800 ≤ w ≤ 60,000

G 2800 ≤ w ≤ 3500

H 16,800 ≤ w ≤ 21,000

J 4200 ≤ w ≤ 12,000

K 4200 ≤ w ≤ 21,000

First you want to find how many words she types per hour.

There are 60 minutes in 1 hour.

So multiply 70 words/min times 60 min / 1 hr to cancel out the minutes.

You will get 4200 words / hr

Then multiply 4200 by 4 and 5

use * as multiplication symbol

4200 words/hr * 4 = 16,800 words/hr

4200 words/hr * 5 = 21,000 words/hr

She will type 16,800 - 21,000 words/hr

So Your answer is going to be letter G
