Find the commission on a $1,250 sale with a commission rate of 5%.
Nana76 [90]
Essentially, we must take 5% of $1250. When we drop the percent sign, we move the decimal 2 places to the left, giving .05. Then "of" means multiply. We take $1250 and multiply times .05, giving 
<span>$62..50 </span>

<span>Another way to do it is to take 10%, or $125. </span>
<span>Then 5% is half of that. Half of $125 is $62.50 We can do that by dividing $125 by 2. I did it in my head. Others might do it on paper. Still others might have a calculator handy and say $125 divided by 2 on the calculator. We should all get the same answer unless one person spaces out or is tired. It happens!</span>

Can someone plzz help me you got to zoom in !!!
daser333 [38]

1. 140 - The reason it would be one 40 is honestly a really simple explanation. Is the ratio of boys to girls in 7-2 and the amount of girls is 40. That means that per 1 number, is 20 people since 40 divided by 2 is 20. So if I do 2 x 7 that would be 140.

2. I didnt really understand this one sorryyy.

3. 1200 (same rule applies) - Since The ratio is 1:11 and the 1 represents 100 beans. If I doo 100 x 11 that would be 1100, then I would add the 1100 to the 100 (from the 1) and that would be 1200.

4. 6:7 - If I do 650 - 350 that would be 300. Which means the ratio would be 300:350. But once simplified the answer would be 6:7.

5. 1:2 - 720 - 240 is 480. Therefore the ratio would be 240:480. Once simplified, the ratio is 1:2.

Hope this helped. Good luck!!! xo

Lace edging is sold by the foot for $0.80 or by the foot for $1.99. Which is more expensive
vampirchik [111]

Answer:

$1.99 is more expensive.

Step-by-step explanation:

Given:

One type of lace edging cost $0.80 per foot

Another type of lace edging cost $1`.99 per foot.

We need to find which is more expensive.

In $0.88 where one's place is 0.

In $1.99 where one's place is 1.

By comparing the one's place obviously $1.99 more expensive.

Hope you will understand the concept.

Thank you.
