Lake has a total of $10,000 to invest in two accounts. One account earns 1% simple interest, and the other earns 10% simple inte

Elza [17]

Answer:

$8000 at 1%
$2000 at 10%

Step-by-step explanation:

It often works well to let a variable represent the amount invested at the higher rate. Then an equation can be written relating amounts invested to the total interest earned.

<h3>setup</h3>

Let x represent the amount invested at 10%. Then 10000-x is the amount invested at 1%. The total interest earned is ...

0.10x +0.01(10000 -x) = 280

<h3>solution</h3>

Simplifying gives ...

0.09x +100 = 280

0.09x = 180 . . . . . . . subtract 100

x = 2000 . . . . . . divide by 0.09

10000 -x = 8000 . . . . amount invested at 1%

$8000 should be invested in the 1% account

$2000 should be invested in the 10% account

<h3>Answer: 17</h3>

======================================================

Explanation:

This is a piecewise function. It's composed of 3 pieces of other functions. A piecewise function is a function that changes its identity based on what the input is.

We have three different situations here

If t = 17, then h(t) = sqrt(17t) based on what the first row says
If t = 19, then h(t) = -34/t which is the second row of the piecewise function.
If t does not equal either 17 or 19 (ie t is anything but those values), then h(t) = 23-t

The notation h(17) means we want to evaluate h(t) when t = 17. So we'll use the first case mentioned above. Plug t = 17 into h(t) = sqrt(17t) to get...

h(t) = sqrt(17t)

h(17) = sqrt(17*17)

h(17) = sqrt(17^2)

h(17) = 17

In the last step, I used the rule that sqrt(x^2) = x when x is nonnegative.

Caspar bought 8 more jelly donuts than chocolate donuts. He bought 5 times as many jelly donuts as chocolate donuts. How many ch

TiliK225 [7]

Answer:

10 chocolate donuts were bought.

Step-by-step explanation:

Given data:

Caspar bought 8 more jelly donuts than chocolate donuts.

He bought 5 times as many jelly donuts as chocolate donuts.

<em>In order for us to answer the we need to make equation from the statements given</em>

Let jelly donuts be denoted by X

Let chocolate donuts be denoted by Y

From this statement <em>'Caspar bought 8 more jelly donuts than chocolate donuts.'</em>

<em>X +8 = Y </em><em>(equation 1)</em>

From this statement 'He bought 5 times as many jelly donuts as chocolate donuts.'

5X = Y <em>(equation 2)</em>

<em>Solving simultaneous equations using the method of substitution.</em>

<em>Substituting equation 2 into equation 1</em>

X + 8 = 5X

8 = 5X - X

8 = 4X <em>(Making X the subject of formula by dividing both sides by 4)</em>

2 = X

<em>Substituting X into equation 2</em>

Y= 5 * 2

Y = 10
