Answer: 40</h3>
Explanation
We can only keep one of the digits: either the tens digit or the units digit. If we kept only the units digit, then we go from 39 to 9 which is a very steep drop. If we kept the tens digit then we go from 39 to 30
The 0 in the "30" is not significant. It's just a placeholder to help us tell 30 apart from simply 3. The drop from 39 to 30 is much smaller (compared to from 39 to 9). But you can probably see that it's even better to bump up to 40 instead, due to the smaller change.
In short, 39 rounds up to 40 when rounding to one significant digit.
If you were to find the price estimate flooring for a room, you would first find the square measurements of the room. This means you need to fine the area of the room in feet. For example, you have a perfect square room with two sides that equal 15 ft. You multiply those two sides so the estimate square footage of the room is 300 square feet.
Depending on the price of the flooring you want, you then multiply the cost of the flooring by 300 square feet to get a estimated price.
I hope this helps!
