Javier bought a paining for $150. Each year the paintings value increases by a factor of 1.15. Which expression is the paintings value after seven years

399.002982

Step-by-step explanation:

150X1.15^7=399.002982

Step-by-step explanation:

Each year the paintings value increases by a factor of 1.15. It means that the rate at which the value is increasing is exponential. We would apply the formula for exponential growth which is expressed as

y = b (1 + r) ^t

Where

y represents the value of the painting after t years.

t represents the number of years.

b represents the initial value of the painting.

r represents rate at which it is increasing.

From the information given,

b = $150

1 + r = 1.15

t = 7 years

Therefore, the expression for the value of the paintings after 7 years is

y = 150 (1.15) ^7
