6. Marilyn collects old dolls. She purchases a doll for $450. Research shows this doll's value will
increase by 2.5% each year. Write an equation that determines the value, V, of the doll tyears after
purchase. Assuming the doll's rate of appreciation remains the same, will the doll's value be doubled in
20 years? Justify your reasoning.

Respuesta :

The equation that determines the value, V, of the doll years after purchase will be V=450(1.025)²⁰. The value of the V will be $ 737.35.

What is the equation?

A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

The fact that the exponential growth function's equation is provided by;

y=a(1+r)ˣ

Y represents the doll's worth.

The number of years is x=20

a is the starting point = $450

The rate of change is r=  2.5% =  0.025

Put the given values;

y=a(1+r)ˣ

y=450(1+0.025)²⁰

y= $ 737.35

Hence, the equation that determines the value, V, of the doll years after purchase will be V=450(1.025)²⁰. The value of the V will be $ 737.35.
