Answer:
Step-by-step explanation:
for this case we have the following model for the cost of the car:
Where is the initial amount on this case 17000, t the amount of years after the initial year and r the depreciation rate on this case:
And for t =14 we can replace into the equation and we got:
Q9.
This question can't be answered. It is necessary to get the dimensions of the figure.
Q10.
Let's find a conclusion having statements step by step.
a) If 3 cans of soup cost a total of $0.85, then 1 can of soup costs:
b) If I get n cans of soup the equation I need to use is multiply the previous equation by n:
The conclusion is: G. Multiplying n by the cost of 1 can.
Q11.
Let's find a conclusion having statements step by step.
a) The company charges $40 to hook a vehicle, so this is a constant variable. Then:
c = 40$
b) There is a second statement that states that for each mile the vehicle is towed the cost increases $1.70, so:
c = $40 + 1.70m
So, the answer is B.
