Multiply 270 × 7/100, which equals to 18.9, and then subtract 270 - 18.9, which gives you 251.1.
X = (1/2)y + 6
x + y = 21
Substitute (1/2)y + 6 as x into the equation x + y = 21 since x = (1/2)y + 6.
[(1/2)y + 6] + y = 21
0.5y + 6 + y = 21
1.5y = 15
y = 10
Same thing, now substitute 10 as y in the other equation.
x + y = 21
x + (10) = 21
x = 11
Answer:
Step-by-step explanation:
<u>Initial value of house:</u>
<u>Yearly increase rate of value:</u>
<u>Time </u>
Since the increase is concerning the current price it would be exponential growth.
<u>The function would be:</u>
- V(t) = 184000*(1 + 3.5/100)^t, where V is the value after t years
<u>For t= 13 we get:</u>
- V(13) = 184000*(1.035)^13 = 287800
<u>Profit made would be:</u>
Correct option is D.
