Answer:

Step-by-step explanation:

24 purple

green : purple = 1 : 3

g / p = 1/3

g / 24 = 1/3

g = 24/3

g = 8

now abbi put x green crayons into box

now green : purple = 5 : 8

(8 + x) / 24 = 5/8

8 + x = 5/8 * 24

8 + x = 5 * 3

8 + x = 15

x = 15 - 8

x = 7

6,000 dollars is invested in two different accounts earning 3% and 5% interest. At the end of one year, the two accounts earned

kap26 [50]

Answer:

$2000

Step-by-step explanation:

6,000 dollars is invested in two different accounts earning 3% and 5% interest.

Let x be the amount invested in account earning 3% interest

So, 6000-x is the amount invested in account earning 5% interest

$S.I. =\frac{P\times R\times T}{100}$

So, Simple interest for account earning 3% interest

$S.I. =\frac{x \times 3 \times 1}{100}$

$S.I. =0.03x$

Simple interest for account earning 5% interest

$S.I. =\frac{(6000-x) \times 5 \times 1}{100}$

$S.I. =0.05(6000-x)$

$S.I. =300-0.05x$

Since we are given that the two accounts earned $220 in interest

So, $0.03x+300-0.05x=220$

$−0.02x+300=220$

$80=0.02x$

$\frac{80}{0.02}=x$

$4000=x$

So, 4000 was invested at 3%

(6000-x)=6000-4000=2000 was invested at 5%

Hence 2000 was invested at 5%

Emily deposited $5,000 into a savings account 6 years ago. The simple interest rate is 3%. How much money did Emily earn in inte

Rainbow [258]

Answer:

$900

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 5000 × 0.03 × 6 = 900

I = $ 900.00

The simple interest accumulated

on a principal of $ 5,000.00

at a rate of 3% per year

for 6 years is $ 900.00.
