Answer:
After 2.80 years the price drops to 300 $
Step-by-step explanation:
Ryan bought a new computer for $2,100.
Price of computer = 2100 $
The value of the computer decreases by 50% each year.
Let p(n) be the price of computer after n years.

Now we need to find n when price is 300 $.
0.50ⁿ x 2100 = 300
0.50ⁿ = 0.143
n log (0.5) = log 0.143
n x -0.301 = -0.845
n = 2.80
After 2.80 years the price drops to 300 $
Answer:
(8 + 24) - (12 x 4)
Step-by-step explanation:
First, we need to set up the equation.
y = amount
x = new customer
Daniel gets 10 dollars each week. Let's think of this as a base pay, there's no variable to it.
So we start with 10.
Next, we have 3.50 dollars each week for each new customer.
So that would be 3.50 times each new customer which would become 3.50x
When you put those two together, you get y = 10 + 3.50x.
The length would be 9 and the width would be 3
