A car was sold for £2,975 after a 7% reduction in price. what is the original value?
Question asked by: knowitall
This is a percentage change question - obviously I'm not going to give you the answer and do all the work for you.
But here is a hint: find the formula for percentage change and then simply apply it to the particular numbers here. This way you will learn the method and be able to do percentage changes in future rather than just get the answer and have all the work done for you!

Don't get complicated about a simple problem.
To reduce the price from the original x by 7% he used the following formula:
x=x * (1 - 0.7)
to find the original price reverse the formula
x=2975 / (1 - 0.7)
x (original price)= 3198.92

ACTUALLY.......... I think everyone else has got it wrong (or they just typed it in a bad way). And we'll change the pounds to dollars, eh? There is a very simple way to get the answer. 7% had been taken off the first price. Therefore, $2,976 is just 93%. Divide $2,975 by 93, to get one percent of the first number, then times it by 100 to get 100% of the first price. There is your answer. But you have to figure it out for yourself. Use a calculator if your not sure. Just because my name is Calcuchic, doesnt mean I do the work for you.

Its simple.. right first
find 10% of 2975 which is 297.5 then find 5%
just half 297.5 which come 2 148.75 now u got ur 5%.. now find 1 of 2975 which is 29.75 to get 2% times 29.75 by 2 which is 59.5 now u have ur 2%
5%(148.75) + 2%(59.5) = 7% (208.25)
so just add 208.25 to 2975 = 3183.25
its long coz i explaned everthing..

Let x represent the total amount.
7/100 = 2975/x (cross multiply)
7x = 297500 (divide both side by 7 to find x)
7x/7 = 297500/7
x = 42500
