The problem can be represented by the the exponential growth formula which is :

Where: t ⇒ time , A ⇒ initial amount , r ⇒ rate of increase
P(t) ⇒ predicted amount at the end of t.
For the given problem:
initial amount = A = $278,640
<span>predicted increase in value per year = 4% =0.04
</span>
<span>∴ r = 1 + 0.04 = 1.04
</span>
<span>for t = 18 years
</span>
∴

<span />
Rounding to the nearest dollar ⇒ ∴ P(t) = <span>564,474
</span>
So, the predicted value of David's home in 18 years = $564,474
So, The correct option is <span>
$564,474</span>

Answer:
1) x= -2
2) x= 3
3) x=7
4) x>5
5) x=-14
Step-by-step explanation:
1) −3x − 3 −7x = 17
−10x−3=17
−10x=17+3
−10x=20
x= -20/10
x=-2
2) 10x − 6 = 24
10x=24+6
10x=30
x= 30/10
x= 3
3) −4−5x=−39
−5x=−39+4
−5x=−35
x=-35/-5
x= 7
4) 3x - 5 > 10
3x>10+5
3x>15
x>15/3
x>5
5) -5 + x + 16 = -3
x+11=−3
x=−3−11
x=-14
7.5/18=15/x
Cross multiply
7.5x/270
Divide both sides by 7.5 to get x alonex=36
Hope that helps! :)
