a jacket is marked down by 15% and is now priced at $85. what was the original price of the jacket? $85 $110 $90 $100 $120
Answer
Explicación:
Paso1: Definir la relación
Sea $x$ el precio original. El precio actual es $(1 - 0.15)x$. $$(1 - 0.15)x=85$$
Paso2: Resolver para $x$
Dividir ambos lados por $0.85$. $$x=\frac{85}{0.85}$$ $$x = 100$$
Respuesta:
D. $100$
