37 = 2/3x - 1
37 + 1 = 2/3x
38 = 2/3x
38 / (2/3) = x
38 * 3/2 = x
114/2 = x
57 = x <=== when complete, the highway will be 57 miles

The original value of a sculpture is $950, and the value decreases by 15% each year. Find the value of the sculpture in 8 years.
german

Answer:

The value of the sculpture in 8 years is $258.865

Step-by-step explanation:

The original value of sculpture = $950

we are given that the value decreases by 15% each year.

Formula : N(t)=N_0(1-r)^t

Where N(t)=Value after t years

N_0 = Initial value

r = rate of decrease in decimals

t = time

We are supposed to find  the value of the sculpture in 8 years.

Substitute the values in the formula :

So,N(t)=950(1-0.15)^8=258.865

Hence the value of the sculpture in 8 years is $258.865
