What is the interest rate of each investment if The annual interest on a $17,000 investment exceeds the interest earned on an $8

Butoxors [25]

<u>Solution-</u>

Let's assume, the rate of interest of $8000 is x%,

then the rate of interest of $17000 is (x+0.3x) =1.3x%

Interest earned by $8000,

$i_1=\frac{8000\times x\times 1}{100} =80x$

Interest earned by $17,000,

$i_2=\frac{17000\times 1.3x\times 1}{100} =221x$

According to the question,

$\Rightarrow i_1=i_2+276$

$\Rightarrow 221x=80x+276$

$\Rightarrow 221x-80x=276$

$\Rightarrow 141x=276$

$\Rightarrow x=1.96$

∴ Rate of interest of $8000 is 1.96% and rate of interest of $17000 is (1.3×1.96) =2.55%

Each sister bought a gift for their mom. Maggie spent 3 times as much as Karen. Karen spent half as much as Jasmine. Altogether,

snow_tiger [21]

Answer:

Maggie spent =30

Karen spent = 10

Jasmine spent =20

Step-by-step explanation:

In this we use algebra to solve.we give the sisters unknowns, to help us solve the equation.

we dont know how much jasmine used so we give her the unknown x.you can use any letter but ill us x.

karen used half as much as karen so we give her 1/2x because it was half of jasmine.maggie used 3 times that of karen so w give her 3(1/2x).

maggie =3(1/2x)

Karen =1/2x

jasmine =x

3(1/2x) + 1/2x + x = 60

3/2x + 1/2x + x = 60

2x + x = 60

3x=60

x=20

where we have x =we replace with 20

e.g karen 1/2x => 1/2 x 20 =10

if you need any clarifications please do tell me in the comment section.i would like to help more if you need help.thx

Hope this helps and if it does mark as branliest anwer thx

Using conversions of mixed numbers, the numbers that are equivalent to 2 and 7/9 are given by:

25/9 and 2.777.

<h3>What are the conversions of the mixed number 2 and 7/9?</h3>

To convert to decimal, we just add the integer part with the fractional part converted to decimal(dividing the numerator by the denominator), hence:

2 and 7/9 = 2 + 7/9 = 2.7777.

To convert to fraction, the procedure is similar, we just apply the least common multiple to add the fraction, as follows:

$2 + \frac{7}{9} = \frac{2 \times 9 + 7}{9} = \frac{25}{9}$

Hence the numbers that are equivalent to 2 and 7/9 are given by:

25/9 and 2.777.
