Answer:

the answer should be 210 dollars because first of all remember that when we are dealing with this problems of percents we need to divide first the percent which is 50% by 100 and you will get 0.50 so then you multiplied it.

0.50 times 420= 210

210 is the correct answer and have a great day.

Steve has $25,000 to invest and wishes to earn an overall annual rate of return of 8%. His financial advisor recommends that h

Alexeev081 [22]

Answer:

<em>Steve should place $6,250 in the 5-year CD and $18,750 in the corporate bond</em>

Step-by-step explanation:

<u>System of Equations</u>

We need to find how Steve will distribute his investments between two possible options: one of them will pay 5% per annum and the other will pay 9% per annum. We know Steve has $25,000 to invest and wants to have an overall annual rate of return of 8%.

Let's call x to the amount Steve will invest in the CD paying 5% per annum and y to the amount he will invest in a corporate bond paying 9% per annum.

The total investment is $25,000 which leads to the first equation

$x+y=25,000$

If x dollars are invested at 5%, then the interest return is 0.05x. Similarly, y dollars at 9% return 0.09y. The overall return is 8% on the total investment, thus

$0.05x+0.09y=0.08(x+y)$

Rearranging:

$0.05x+0.09y=0.08x+0.08y$

Simplifying

$0.01y=0.03x$

Multiplying by 100

$y=3x$

Substituting in the first equation

$x+3x=25,000\\4x=25,000\\x=6,250$

And therefore

$y=25,000-6,250=18,750$

Steve should place $6,250 in the 5-year CD and $18,750 in the corporate bond

Sara earned $7.25 per hour plus an additional $105 in tips waiting tables last week. She earned at least $329.75. If h

jonny [76]

Answer:

The minimum number of hours that Sara could have worked is 31 hours .

The inequality representation of possible value of h is 105 + 7.25 h $\geq$ 329.75

Step-by-step explanation:

Given as :

The earning of Sara in per hour amount = $7.25 per hour

The additional earning of Sara as tips = $105

The Total earning of Sara = $329.75

Let The minimum number of hours that Sara could have worked = h hours

<u>Now, According to question</u>

The Total earning of Sara = The earning of Sara in per hour amount × minimum working hours + The additional earning of Sara as tips

I.e $329.75 = $7.25 per hour × h + $105

Or, $105 + $7.25 per hour × h = $329.75

Or, $7.25 per hour × h = $329.75 - $105

Or, 7.25 per hour × h = 224.75

∴ h = $\dfrac{224.75}{7.25}$

I,e h = 31 hours

So, The number of hours Sara worked = h = 31 hours . Answer

Hence, The minimum number of hours that Sara could have worked is 31 hours .

The inequality representation of possible value of h is 105 + 7.25 h $\geq$ $329.75

Inequality the difference of2and a number is at least negetive 1

geniusboy [140]

An inequality where the difference between 2 and a number is at least negative 1 will be x - 2 ≥ -1.

<h3>What is the inequality?</h3>

The first part of the inequality is that there is a difference between a number and 2.

Assuming that number is 2, the first part is:

x - 2

The result of this subtraction at least negative 1. When a number is at least a number, it means that it is either that number or larger.

So the total inequality is:

x - 2 ≥ -1
