Part A:
(3x+5)+(3x+5)+(4x-3)+(4x-3)=p
3x+3x+4x+4x=14x
5+5+-3+-3=4
14x+4=p
-4 -4
14x=p-4
---- -----
14 14
x=1/4 p + -2/7
14(1/4 p +-2/7) +4=p
14(0.25p + 0.28571428571)+4=p
3.5 + 3.99999999994 + 4=p
11.4999999999=p
This may not help by no harm in trying.
Answer:
C y = 20x +40
Step-by-step explanation:
I think there is a typo in your question
monthly payment total = 20 x
total paid so far = 40 + 20x
y = 20x + 40
Answer:
0
Step-by-step explanation:
Put -6 where x is and do the arithmetic.
f(-6) = 1/3 (-6 +6) = 1/3 (0)
f(-6) = 0
Answer:
The current price of the unit trust = £13,831.72
Step-by-step explanation:
Since it increased 7% per annum in last three years and decreased by 3% per annum before that, it implies that the unit trust decreased by 3% per annum for the first 2 years and then increased by 7% per annum for the next 3 years in the total 5 year period
The invested after 2 years = 12,000*(1-0.03)^2 = £11,290.8
This amount then grows by 7% for the next 3 years making it = 11,290.80*(1+0.07)^3 = £13,831.7155 = £13,831.72 (Rounded to 2 decimals)
The current price of the unit trust = £13,831.72 (Rounded to 2 decimals)
