1 is in the denominator,

so we divide top and bottom by 2

3 miles ÷ 2

2 hours ÷ 2

1.5 miles

1 hour

1.5 miles

hour

statuscvo [17]

Answer:

The function is correct, I just don't see a question.

Step-by-step explanation: 6 21 6 10

C(n) = 12n + 65

I will make up a question. How much will it cost 4 people each to rent the cabin?

C(n) = (12n + 65) / n n = 4

= (12 × 4 + 65) / 4

= (48 + 65) / 4

= 113 / 4

= $28.25

If your question is differnt just substitute the number of people into the question and solve for C(n)

After breaking your penny bank, you notice that you have $4.87 in quarters ($0.25), dimes ($0.10), nickels ($0.05), and pennies

Answer: Option 'c' is correct.

Step-by-step explanation:

Let the number of dimes be 'x'.

Let the number of nickels be ' $\dfrac{3}{2}x$ '.

Let the number of pennies be $\dfrac{3}{2}\times 2x=3x$

Let the number of quarters be '3x-34'.

As we know that

1 quarter = $0.25

1 dime = $0.10

1 nickel = $0.05

1 penny = $0.01

According to question, we get that

$0.10x+0.05\times \dfrac{3x}{2}+0.01\times 3x+0.25(3x-34)=4.87\\\\0.10x+0.075x+0.03x+0.75x-8.5=4.87\\\\\\0.955x=4.87+8.5\\\\0.955x=13.37\\\\x=\dfrac{13.37}{0.955}\\\\x=14$

So, the number of pennies is given by

$3x=3\times 14=42$

Hence, Option 'c' is correct.
