Answer 1

Data

• Original price (,O,): $420

,

• Original price percent (,PO,): 100%

,

• Really paid (,R,): $120

,

• Really paid percent (,x,): ?

Procedure

We have to build a relationship taking into account the parameters given:

`(420)/(100)=(120)/(x)`
`4.2=(120)/(x)`

Isolating for x:

`x=(120)/(4.2)`
`x\approx28.57`

Answer: 28.57
