Answer:

c.

$14,000

Step-by-step explanation:

Let x be the value of the home

We can use a ratio to solve

.27         insurance

------ = -----------

100            x

.27         683.10

------ = -----------

100            x

Using cross products

.27x = 100 *683.10

.27x=68310

Divide by .27

x = 68310/.27

x = 253000

This is the original value of the home

Now using the new premium

.27         720.90

------ = -----------

100            x

.27x = 720.90*100

.27x = 72090

Dividing by .27

x = 72090/.27

x =267000

The increase is the new value minus the original value

267000-253000

14000

Answer:

  c.  $14,000

Step-by-step explanation:

The increase in Sam's premium was ...

  $720.90 -683.10 = $37.80

The home value increase this corresponds to can be found using the proportion ...

  (value increase)/(premium increase) = value/premium

  (value increase)/37.80 = 100/0.27 . . . . . . . . . . . . fill in known quantities

  value increase = 37.80×100/0.27 = 14,000 . . . . .multiply by 37.80

Sam's home increased in value by $14,000.
