Question

Javier bought a painting for $150. Each year the painting's value increases by a factor of 1.15. What's the expression that gives the painting value after 7 years

Answer 1

Multiply 1.15 times 7 to find the painting value

Answer 2

Answer:

Step-by-step explanation:

Each year the painting's value increases by a factor of 1.15. This is an exponential growth. We would apply the formula for exponential growth which is expressed as

A = P(r)^t

Where

A represents the value of the painting after t years.

t represents the number of years.

P represents the initial value of the painting.

r represents rate of increase.

From the information given,

P = $150

t = 7 years

r = 1.15

Therefore, the expression that gives the painting value after 7 years is

A = 150(1.15)^7
