KengaRu [80]

Answer:

6 : 23

Step-by-step explanation:

a : b = 3 : 4 ....(given)\\  \\ let \: a = 3x \\ b = 4x \\  \\ (6a - 3b) : (5a + 2b) \\  \\  =  \frac{(6a - 3b)}{(5a + 2b)}  \\  \\  = \frac{6(3x) - 3(4x)}{5(3x) + 2(4x)} \\  \\  =  \frac{18x- 12x}{15x+ 8x} \\  \\  = \frac{6x}{23x} \\  \\  =  \frac{6}{23}  \\  \\ (6a - 3b) : (5a + 2b) = 6  : 23

Stephanie has a homeowners insurance policy for her $355,000 home with an annual premium of $0.42 per $100 of value and a deduct
frosja888 [35]

Answer:

$0.28 per 100 of value (B)

Step-by-step explanation:

Stephanie has a homeowner insurance policy of $355,000

Annual premium = $0.42 per 100

There is a deductible of $500

Stephanie has an annual out of pocket expense of

[($355,000/100) x $0.42] + $500 = $1,991

From the question, Stephanie now wants a new deductible amount of 1000.

Let X be the new annual premium

[(355,000X) / 100] + 1000 = 1991

3550X + 1000 = 1991

3550X = 1991 -1000

3550X = 991

X = 991/3550

X = 0.2791

X = 0.28 ( approximately)

The new annual premium is $0.28 per 100 of value
