Question

Find the original price of a computer that after a 20% increase sells for $890.

Answer 1

hi

let's call X the orignal price.

to rise a price of T% is to multiply it by 1 +T/100

Now what we know ?

we have according to initial data :

T =20 so increase factor is 1+ 20/100 = 1.2

So : 1.2 X = 890

X = 890 /1.2

X = 741.67

Original price is 741.67 dollars

Lets'check :

20% of 741.67 is : 741.66 *0.2 = 148.33

so : 741.67 +148.33 = 890
