If a delorian was worth 25,000 in 1985 and it appreciates in value 1.25% every year, how much was it worth in 1955

So for this, we will create an equation using the exponential growth formula - which is , where a = initial value and b = growth/decay

So for this problem, let year 1985 be the initial year. Since it's the initial year, 25000 is our a variable.

Now, since the value is appreciating, or increasing, we will add 1 and 0.0125 (1.25% in decimal form) together:

1.0125 is our b variable.

Now with our info, our equation is:

Now, since 1955 is 30 years before 1985, plug -30 into the x variable and solve as such:

In short, the value of the item was $17,222.22 in year 1955.

the temperature will be -18 just do 62 + (-40) + (-40)
