$12.50x+17.50y=1535\n x+y=110\n\n 12.50x+17.50y=1535\n x=110-y\n\n 12.50(110-y)+17.50y=1535\n 1375-12.50y+17.50y=1535\n 5y=160\n y=32\n\n x=110-32\n x=78$

What is the ratio of people who prefer oranges to bananas?

Answers

I saw the pie chart that should have accompanied this word problem.

Favorite fruit:
Grapes = 150
Apple = 220
Orange = 185
Banana = 235

Choices:
A) 37/47
B) 185/790
C) 790/275
D) 235/185

Oranges = 185 ; Bananas = 235

Ratio of oranges to Bananas = 185/235
Simplify 185/235
185 ÷ 5 = 37
235 ÷ 5 = 47

Ratio of oranges to Bananas = 37/47 Choice A.

24. Congratulations! You have just won a jet ski worth $8000. The depreciated value of the jet ski (V) after t years is given by V = 8000 − 725t , 0 ≤ t ≤ 11.a. Use a graphing utility to graph the equation. Include a t-chart with at least 5 key points with your accurate labeled graph.
b. After how many years will the jet ski be worth $5100? Show all of your work or explain how you came up with your answer.
c. What will be the value of the jet ski after 9 years? Show all of your work or explain how you came up with your answer.

Answers

So:

$V=8000-725t\quad \{ 0\le t\le 11\}$

*V (in dollars) stands for the depreciated or non depreciated value of the jet ski.

*t (in years) stands for the amount of time that has passed. t is greater or equal to 0 and less than or equal to 11.

-------------------

Question (a):

Now V is a function of t. V=f(t).

When t=0, V=0 --> Point:(0,0)

When t=2, V=6550 --> Point (2, 6550)

When t=4, V=5100 --> Point (4, 5100)

When t=6, V=3650 --> Point (6, 3650)

When t=8, V=2200 --> Point (8,2200)

When t=11, V=25 --> Point: (11, 25)

So as the graph V=8000-725t is LINEAR, we can draw a line through the points mentioned above.

------------------------

Question (b): After how many years will the jet ski be worth $5100?

$8000-725t=5100\n \n 8000-5100=725t\n \n 2900=725t\n \n \frac { 2900 }{ 725 } =t\n \n \therefore \quad t=4,\quad when\quad V=5100$

Answer: 4 years.

-----------------------

Question (c): What will be the value of the jet ski after 9 years?

$When\quad t=9,\n \n V=8000-725\left( 9 \right) \n \n =1475$

The answer is $1,475.00

a) $y=mx+c$
$m=gradient=-725$
$y(v)-intercept=8000$

b) $5100=8000-725t$
$2900=725t$
$t=4$
The value will be 5100 after 4 years.

c) $V=8000-725(9)$
$V=8000-6525$
$V=1475$
The value of the jet will be 1475 after 9 years.
