1. Suppose Dan received $200 for his birthday. If Dan spent $150 and saved $50: a. what percentage of the $200 did Dan spend? Answer: b. what percentage of the $200 did Dan save? Answer:S 2, a. Solve for X: X = 40 25 50 Answer: X= b. Solve for Y:4%-10-ZY-4 2 Answer:Y 3. What is the percentage increase in rent for a one- bedroom apartment if average monthly rent for a one- bedroom apartment increased from $650 in 2016 to $702 in 2017? Answer When X = 9, Y-6 and when X = 12, Y-8. If the relationship between X and Y is linear, what is the value of Y when X = 1 5? 4. Answer: Y

Explanation / Answer

Question 3). Solution :- Percentage increase in rent = (702 - 650) / 650

= 52 / 650

= 0.08 i.e., 8 %

Conclusion :-  Percentage increase in rent = 8 %

Question 4). Solution :- Calculation of value of Y when X = 15 :-

Y = [ (8 - 6) / (12 - 9) ] * 15

Y = (2 / 3) * 15

Y = 0.66667 * 15

Y = 10.

Conclusion :- When X = 15, Y = 10.

Question 5). a). Solution :- C = 100 + 0.8 (Y - T)

If Y = 1000 and T = 0,

C = 100 + 0.8 * (1000 - 0)

C = 100 + 0.8 * 1000

C = 100 + 800

C = $ 900

Question 5). b). Solution :- C = 100 + 0.8 (Y - T)

If Y = 1000 and T = 100,

C = 100 + 0.8 * (1000 - 100)

C = 100 + 0.8 * 900

C = 100 + 720

C = $ 820.

Conclusion :-

a). If Y = 1000 and T = 0, Consumption (C) $ 900. b). If Y = 1000 and T = 100, Consumption (C) $ 820.
