hello everyone today's topic

is percentage

implementation and our learning

objectives is to solve real life

problems involving percentages and

money and some of the problems that we

will

be learning is decide which product or

service is better value for money and

Carry Out calculations involving money

and lastly we'll be learning how to

convert between

currencies okay so first topic is

comparative cost we're going to cover

how to do Best Buy CS which involve

comparing two items to see which which

one of them is best value for money for

example let's imagine that we had the

option of buying two kinds of apple and

we want to know which one of them was

best value for money Apple Fuji

is 900 G and cost 63,000 rupias whereas

AI is 1 kilg and cost

120,000 th000 rupia which one represent

the best the best value well at the

moment we can't really compare them

because the sizes and costs are both

different so it's hard to see which ones

more expensive to make them comparable

though we need to make either the cost

or the size the same in this case the

easiest way to do that would be to find

out how much each APLE cost per grass so

if we do APLE Fuji

first 63,000 rup

is the price for 900 grams so we need to

divide the 60,000 rupia by

900 grams to find out that it cost 70

rupes per GRS and then we do exactly the

same thing for AP lucky

so

120,000 rupia divided by a kilogram

which is 1,000 G to get 120 rupias per

grams and then by comparing these two

prices we can see that Apple Fuji is

better value because it costs 50 rupia

per GR com s cheaper than apal

lucky okay so next topic is sales

tax this is the tax paid on spending it

is included in the price paid for most

articles in many countries some articles

are free from sales tax for example

children's

cing and to to find the final price

after the sales tax the formula is to

multiply original price by

100% plus the tax

rate okay for example a computer cost

1,200 plus sales tax at 15%

so the question ask us to calculate the

selling

price following the formula above we

will get

,200 time 100% plus

15% which

is

115% so we will get

[Music]

$1,200 times

115 over 100 so the final price of the

computer is

1,0000 I mean

1,380 next topic is income

tax in income tax is paid on money

earned and most government believe that

richer people should pay more tax than

poorer people as a result of this the

amount of tax falls into different rates

or tax

banss in our country Indonesia these are

the tax bands so if you have

an annual salary up to 60 Millions

Indonesian rupia your tax rate will be

5% and if your annual salary is above 60

million to

250 million Indonesian rupia your tax

rate is 15%

and so

on okay for example Maya

earns 6 million Indonesian rupias for a

month as a

veterinarian what is her monthly income

tax bill so to calculate this first we

have to

find how much Maya earns in a year so we

just need to times the monthly

salary by 12 so we've got

72 million Indonesian

rupes and this

is in the second category because it is

above 60 million Indonesian rupes so

first we need to find out

the tax bill for the first

category so

60 million indonation rupias

times

5% which is 5 over 100 so we'll get 3

million Indonesian

rups the remainder of my uh salary

is 72 - 60 and we'll get 12 million

indonation

Ras we times it with the second tax rate

which is

15% 15 over 100

so the second categor tax bill is a

million and

800,000 Indonesian

rupias so the

total income tax bill for Maya in a year

is 3 million plus 1 milon

800 which is equals to

4,800 Indonesian rupia

but the Cent ask for her monthly income

tax bill so we need to divide this total

tax by 12 because in a year there are 12

months so we've got

400,000 Indonesian rupia that means Maya

has to pay

400,000 Indonesian RUP

for her income tax bill for a

month last topic of today's lesson is

foreign

currency different currencies are

exchanged and converted around the world

so an accurate rate of conversion is

needed this this table below shows some

examples of values compared to one

Indonesian

rupia so for example Maya a student from

Indonesia is planning a trip to Japan

she wants to exchange some Indonesian

Ras to Japan Yen Japanese Yen for her

travel

expenses let's say Maya exchanges a

million Indonesian rupes how many

Japanese Yen

that so to calculate

this we use the conversion rates in the

table one Indonesian Ras is equals to

0.0964 Japanese Yen so for a million

Indonesian rupia we just need to times

it

by the conversion rates so 1 million

time

0.0964 Japanese Yen

so Maya will get 9,6

full Japanese Yen
