Ethan invested $9,500 in an account paying an interest rate of 2 3/4% compounded monthly. Henry invested $9,500 in an account paying an interest rate of 3 3/8% compounded quarterly. After 9 years, how much more money would Henry have in his account than Ethan, to the nearest dollar?

Answers

Answer:

691

Step-by-step explanation:

Henry would have $1,005.94 more than Ethan in his account after 9 years.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

To solve this problem, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

where A is the amount after t years,

P is the principal

r is the annual interest rate,

n is the number of times the interest is compounded per year, and

t is the time in years.

For Ethan:

P = $9,500, r = 2.75% = 0.0275 (since it is compounded monthly, n = 12), and t = 9

[tex]A = 9,500(1 + 0.0275/12)^(^1^2^\times^9^)[/tex]

= $12,817.84

For Henry:

P = $9,500,

r = 3.375% = 0.03375 (since it is compounded quarterly, n = 4), and

t = 9

[tex]A = 9,500(1 + 0.03375/4)^(^4^\times^9^)[/tex]

= $13,823.78

The difference in the amounts is:

$13,823.78 - $12,817.84 = $1,005.94

Therefore, Henry would have $1,005.94 more than Ethan in his account after 9 years.

Mark spends $36 at a basketball game. He buys a T-shirt for $22. He then buys a bottle of water for $4 and 2 tacos. How much is each taco?

Answers

Answer:

each taco is $7.

Step-by-step explanation:

In total he spent $36. He bought a shirt for $22 and a bottle of water for $4.

22+4= 26

36-22= 14

14 divided by 2= 7

Answer:

each taco is $5.

Step-by-step explanation:

Let's think about like Mark starts off with $36. Take away $22 for that t-shirt he bought. Now he has $14. He uses $4 for water, now he has $10. The rest of his money is spent on tacos. $10/2 tacos is $5 for each taco. :)

I NEED THE ANSWER THANKS

Answers

Answer:

1. x + 5 = 12

2. 2x = 54

Step-by-step explanation:

Let

The unknown number = x

1. The sum of a number and 5 is 12.

x + 5 = 12

x = 12 - 5

x = 7

2. Twice a number is 54

2x = 54

x = 54/2

x = 27

3. Thrice a number increase by 2 is less than 50.

3x + 2 < 50

3x < 50 - 2

3x < 48

x < 48/3

x < 16

4. One half the sum of a number and 4 is less than 28.

1/2(x + 4) < 28

5. A number increased by one-third of the number is 5.

x + 1/3x = 5

A farmer is creating a budget for planting soybeans and wheat. Planting soybeans costs $200 per acre and planting wheat costs $500 per acre. He wants to spend no more than $100,000 planting soybeans and wheat. What is the "multiplier" for soybeans? ​

Answers

Answer:

5 acres < soybeans < 495

2 acres < wheat < 198 acres

Step-by-step explanation:

If farmer plans to plant minimum of soybeans, it should be 5 acres of soybeans costing $1000. The remaining cost of $98,000 will be available for maximum of wheat, i.e., 198 acres of wheat.

Similarly, if we go for minimum possible planting for wheat, it should be 2 acres, and then resulting in 495 acres for soybeans

5 acres < soyabeans < 495

2 acres < wheat < 198 acres  

Answer:

The multiplier for soybeans is 200, which is dollars per acre.

Step-by-step explanation:

5 acres ≤ soybeans ≤ 495 acres (constraint)

2 acres ≤ wheat ≤ 198 acres (constraint)

150w + 125s = 100,000

This would represent 150 acres of wheat and 125 acres of soybeans. The acres of wheat would add up to $75,000 because 150 x 500 = 75,000 and the acres of soybeans would add up to $25,000 because 125 x 200 = 25,000. (example of a solution, there are more possible)

Hector's family traveled 7 10 of the distance to his grandmother's house on Saturday. They traveled 2 3 of the remaining distance on Sunday. What fraction of the total distance to his grandmother's house was traveled on Sunday?

Answers

Answer: 1 / 5 of the total distance.

Step-by-step explanation:

They traveled 7/10 of the distance on Saturday. This means that on Saturday, the fraction left was:

= 1 - 7/10

= 3/10 of the distance

On Sunday, they traveled 2/3 of this remaining distance. The fraction of the distance traveled is therefore:

= 2/3 * 3/10

= 6 / 30

= 1 / 5 of the total distance.
