To find a number's , let's say "x%" you should multiply that number by, \frac { x }{ 100 } , so we want to find 150 's 20% , so we will multiply , 150 with \frac { 20 }{ 100 } , so :

150\cdot \frac { 20 }{ 100 } \\ \\ We\quad can\quad simplify\quad \frac { 20 }{ 100 } \\ \\ \frac { 20 }{ 100 } =\frac { 2\cdot 10 }{ 10\cdot 10 } =\frac { 10 }{ 10 } \cdot \frac { 2 }{ 10 } =1\cdot \frac { 2 }{ 10 } =\frac { 2 }{ 10 } \\ \\ 150\cdot \frac { 2 }{ 10 } =\frac { 150\cdot 2 }{ 10 } =\frac { 300 }{ 10 } =30\\ \\ %20\quad of\quad 150\quad is\quad 30

Calculate the interest paid when 4920 is invested at 13% p.a simple interest for eight years​
Jlenok [28]

Answer:

I'll setup the problem and you can do the calculations

Step-by-step explanation:

The formula for simple interest:

I = P*r*t

I = interest

P = principle or amount invested

r = interest rate per period (period is a year)

t = number of periods

P = 4920

r = .13

t = 8

Suatu jenis roti memerlukan 150 gram tepung dan 50 gram mentega. Roti jenis lain memerlukan 75 gram tepung dan 75 gram mentega,
Katena32 [7]
Let the one type of the bread be bread A
The second type of the bread be bread B

Let the flour be 'f' and the butter be 'b'

We need 150f + 50b for bread A and 75f + 75b for bread B

We can compare the amount of flour and bread needed for each bread and write them as ratio

FLOUR

Bread A : Bread B
150 : 75
2 : 1

We have a total of 2250gr of flour, and this amount is to be divided into the ratio of 2 parts : 1 part. There is a total of 3 parts. 

2250 ÷ 3 = 750 gr for one part then multiply back into the ratio to get

Bread A : Bread B = (2×750) : (1×750) = 1500 : 750


BUTTER

Bread A : Bread B = 50 : 75 = 2 : 3

The amount of butter available, 1250 gr is to be divided into 2 parts : 3 parts.
There are 5 parts in total

1250 ÷ 5 = 250 gr for one part, then multiply this back into the ratio 

Bread A: Bread B = (2×250) : (3×250) = 500 : 750

Hence, for bread A we need 1500 gr of flour and 500 gr of butter, and for bread B, we need 750 gr of flour and 750 gr of butter.
