Question

I'm having difficulties with this one, can I get some help?

Michael bought a new lawn mower at 30% off for $357. What was the original price of the lawn mower? Please show all work.

Answer 1

100 : 357
70 : x

Answer 2

375 is the 100% price..

now after discount, you have to find the 70% of the ORIGINAL price.
(100-30 = 70)

Now.. Cross multiply. ;)

Answer 3

@ParthKohli , i always get confused in the formula, so i dont use it. :D

Answer 4

\[\Large x - {30x \over 100} = 357 \]
\[\Large {70x \over 100} = 357 \]
\[\Large 70x = 35700 \]
\[\Large x = 510 \]
:D
