--- second discount

Required
Determine the amount paid
First, we add the total discount:



If she got a discount of 40%, then she paid 60% (i.e. 100% - 40%)
So:


Calculate the sales tax




If I counted correctly, the answer would be 52/150. You just need to simplify the fraction. I'll recount soon, and update if it changes.
Answer:
The correct option is, Exponential Decay, $23,914.85.
Step-by-step explanation:
A farmer buys a tractor for $50,000.
It is provided that the the tractor depreciates 10% per year.
The exponential function for decay is:

Here,
a = initial value
r = decay rate
t = time
Compute the value of the tractor in 7 years as follows:


Thus, the correct option is, Exponential Decay, $23,914.85.
Answer:
They are all positive because you must go right.
They are all negative because you must go down.

Answer:
<u>Approximate values according to picture:</u>
<u>The values of given expressions:</u>
- a) a + b + c = 1.6 + 4 + 5.8 = 11.4
- b) c - b + a = 5.8 - 4 + 1.6 = 3.4
- c) c ÷ a + b = 5.8 ÷ 1.6 + 4 = 3.6 + 4 = 7.6 (3.6 is rounded)
