Are you sure Bill was wrong? When i worked it out I got £192 as well lol

The way you do it is

£240 X 0.80

because to get the whole thing you times it by 1 but you want 20 percent less so if you take 20 off 1 you get 0.80... the thing is though £240 X 0.80 is £192

BILL IS WRONG. I WORKED OUT A NOW JUST CONFUSED HOW TO DO B:huh::huh::huh::huh::huh::huh::huh::huh::huh:

Re: HELP ME ON MY HOMEWORK PLEASE
 

Well if she earns 20% more than last year that means its a 120% at the moment.
her loan last year was a 100% therefore 200 dollars
do you understand what i mean?

edit: I mean pounds, sorry

Re: HELP ME ON MY HOMEWORK PLEASE
 

How can you be sure that bill is wrong? By the way you shouldnt have marked this post as triggering because it isnt.

EDIT: On second thoughts, £200 is right... because yeah she is currently earning 120%. So you divide £240 by 120 to get 1% which is 2. You then multiply 2 by 100 to get the full amount which is 200.

Well done Hanna :)

i dont get it. i dont think you're right

and bill is wrong because it says in the question

Re: HELP ME ON MY HOMEWORK PLEASE
 

Thanks Jen
and dom i can assure you its right.
You take last years salary as a basis, thats a 100%
now he gets 20% more so now he earns 120% which is 240 pounds
therefore 100% is 200 pounds

Re: HELP ME ON MY HOMEWORK PLEASE
 

how do you find 100% of 240?

get it now i think

for a would the answer be








BILL HAS FOUND 20% OF HAJRA'S WEEKLY PAY THIS YEAR INSTEAD OF FINDING 20% OF HER EARNINGS THE PREVIOUS YEAR.



i got this answer then realised b was all wrong so not sure if A is right

Re: HELP ME ON MY HOMEWORK PLEASE
 

Well there is an easier way than i do it but i divided 120 through 100 and got 1.2
and then i divided 240 through 1.2 and got 200
basically 120% equals 240 pounds, but you need 100%, so you need to look what factor you candivide 120 with to get 100 and use that factor to get from 240 to the number you need. at school i write it like this
120% = 240
100% = x and then do the calculations
sounds a bit complicated, theres an easier way though
you calculate this 240:120*100

Re: HELP ME ON MY HOMEWORK PLEASE
 

240:1,2=200

(240=120%)

x+ 0.2x=240
x=200
