An amusement park charges a $12 parking fee plus 25 per person. What is the total cost for 32 people?​
icang [17]

Answer:

The total amount for 32 people is 15.36

Step-by-step explanation:

we know that for 25 people is $12 so we need to find how much it would be for one person. you would need to divide $12 / 25. from this you would get 0.48, so for one person it's 48 cents. next you're going to subtract 25 from 32, this leaves you with seven people who aren't in a group of 25. you then multiply 7 × this equals to 3.36, add 3.36 to $12 and you'll get your total 15.36.

Which of the following is equivalent to 2 ln e^ln 5x = 2 ln 15?
neonofarm [45]

Answer:

x  = 3

Step-by-step explanation:

Given in the question an equation,

2lne^{ln5x}=2ln15

Step 1

e^{lnx}=x

so,

2ln(5x)=2ln15

Step 2

cancel 2 on both sides of the equation

ln{5x}=ln15

Step 3

ln{5x}-ln15=0

ln\frac{5x}{15}=0

Step 4

ln\frac{x}{3}=0

Step 5

e^{ln\frac{x}{3}}=e^{0}

Step 6

x/3 = 1

x = 3(1)

x = 3

A boat costs $11,850 and decreases in value by 10% per year. How much will the boat be worth after 8 years?
arsen [322]
11,850 x .9 = 11,605  

11605 x . 9 = 9,598.5       year 2 

9,598.5 x .9 = 8,638.65

8,635 x .9 = 7,774.785       year 4

7,774.785 x .9 = 6,997.31

6,6997.31 x .9 = 6297.58     year 6 

6297.58 x .9 = 5,667.82 

5,667.82 x .9 = 5,101.04 year 8 

The answer is D
