f(t) = 2(0.4)^t
F(-2) means to replace t with -2:
f(-2) = 2(0.4)^-2
f(-2) = 12.5

Solve Applications with Linear Inequalities
Many real-life situations require us to solve inequalities. In fact, inequality applications are so common that we often do not even realize we are doing algebra. For example, how many gallons of gas can be put in the car for ?20? Is the rent on an apartment affordable? Is there enough time before class to go get lunch, eat it, and return? How much money should each family member’s holiday gift cost without going over budget?
The method we will use to solve applications with linear inequalities is very much like the one we used when we solved applications with equations. We will read the problem and make sure all the words are understood. Next, we will identify what we are looking for and assign a variable to represent it. We will restate the problem in one sentence to make it easy to translate into an inequality. Then, we will solve the inequality.
Emma got a new job and will have to move. Her monthly income will be ?5,265. To qualify to rent an apartment, Emma’s monthly income must be at least three times as much as the rent. What is the highest rent Emma will qualify for?

65000 that is the right answer
Answer: The correct option is (B) 1625.2 miles.
Step-by-step explanation: Given that at a given speed a car can travel 95.6 miles on 4 gallons of gasoline.
We are to find the distance that the car can travel on 68 gallons at the same speed.
We will be using the UNITARY method to solve the given problem.
Distance traveled by the car on 4 gallons of gasoline = 95.6 miles.
So, the distance traveled by the car on 1 gallon of gasoline will be
Therefore, the distance traveled by the car in 68 gallons of gasoline is given by
Thus, the required distance traveled by the car on 68 gallons of gasoline is 1625.2 miles.
Option (B) is CORRECT.
