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:

$\frac{420}{100}=\frac{120}{x}$$4.2=\frac{120}{x}$

Isolating for x:

$x=\frac{120}{4.2}$$x\approx28.57$

Answer: 28.57
