Answer:

number = 8

Step-by-step explanation:

Let "number" = x. Set the equation.

"product of 2 and number" = 2(x)

"nine less" = -9

"equal to 7" = "= 7"

2x - 9 = 7

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 9 to both sides.

2x - 9 (+9) = 7 (+9)

2x = 7 (+9)

2x = 16

Divide 2 from both sides.

(2x)/2 = (16)/2

x = 16/2

x = 8

8 is your answer.

Marcos purchased a sail boat for $56,900. He anticipates each year the boat will decrease in value by 8.1% from the previous yea

Varvara68 [4.7K]

Answer: $56,900\left( 0.919\right)^x$

Step-by-step explanation:

Given

Marcos purchased a sailboat for $\$56,900$

Each year the boat will decrease in value by $8.1\%$

After 1 year it is

$\Rightarrow 56,900-56,900\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\\$

after another year it becomes

$\Rightarrow 56,900\left( 1-0.081\right)-56,900\left( 1-0.081\right)\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\cdot \left( 1-0.081\right)\\\Rightarrow 56,900\left( 1-0.081\right)^2$

After $x$ years it is

$\Rightarrow 56,900\left( 1-0.081\right)^x$

$\Rightarrow 56,900\left( 0.919\right)^x$
