18000 represents the price of the new car.
The value of the car in 6 years can be found by substituting 6 for the variable t, as follows:
In 6 years, it will be worth around $8359.27.
The equation for the car worth $20000 is this:
In 6 years, the other car will be worth $7542.99, so the car worth $18000 will have more value in 6 years.
Answer:
Short-response question = 20.
Step-by-step explanation:
Let x be number of short response questions and y be the number of essay questions.
We have been given that there are 22 questions that are worth 100 points in total. Each short-response question is worth 4 points, and each essay question is worth 10 points. Using our given information we can form a system of equations as:
Now we will solve our system of equations using substitution method.
From equation 1 we will get,
Upon substituting in equation 2 we will get,
Therefore, there are 20 short-response questions on the exam.
