During a blood drive, the ratio of Type O donors to non-Type O donors was 37:43. About how many Type O donors would you expect in a group of 300 donors?
Answer:
258
Step-by-step explanation:
Type O: Non-Type O = 37:43
Now we just plug in values!
Type O:300 = 37:43
Now we will do some proportions. Remember that 300x37=Type Ox43, meaning that 11100/43 will give us our answer of 258.139534884, rounding to 258.

Bonnie borrowed $2400 at 6% simple interest for one year. If she makes no payments that year, how much interest will she owe at the end of the year?
Answer: 400
Step-by-step explanation: 2400 divide by 6 which is = to 400
in other way 400x6 = 2400 we just div that.
The interest will she owe at the end of the year is 600.
What is Interest?The fee you pay to borrow money or the fee you charge to lend money is called interest. The most common way to represent interest is as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.
Given:
P= 2400
T= 1 year
SI= 6%
Now, using
SI = PRT/ 100
6 =(2400 x R x 1)/ 100
2400R = 600
R= 600/ 2400
R= 0.25%
Hence, the interest will she owe at the end of the year is 2400 x 0.25 = 600.

Here is my statement about the luxury destinations
National landmarks are popular tourist destinations, and some of them, such as bridges or dams, perform important functions but it costs money to keep these places open for tourists so who is gonna pay? When the governor pays the money comes from people’s taxes most people would rather pay lower taxes so the government has to cut back on its spendings maintaining national landmarks is a luxury we cannot afford. I think there are many more important things that the government can spend on, such as helping people who do not have enough food making sure all children get a good education, and keeping all of us safe but he also spends all of the money on him to or her and there money balance is approximately 75 trillion dollars, why not give some to people in need, fixing building, helping cities, instead of keeping it all to the government agency office everyone shall agree with me becuase they take our money why take money from people who struggle with there bill dum taxes i agree and all of you should to we want our money back and sometimes i struggle to with my home we dont have a job we only get food stamps thats it but we are trying to fix this situation now does everyone agree with me becuase you should now agree until your mouth doesnt move AGREE now bye see ya
