A group of friends wants to go to the amusement
Zepler [3.9K]

Answer:

The maximum amount of people that can go to the amusement park is 15.

Step-by-step explanation:

First you create an equation to represent the question

8.75+25.75x≤420

You put the less than or equal to sign because 420 is the maximum amount of money.

Now you just solve the equation.

25.75x≤420-8.75

25.75x≤411.25

x≤411.25/25.75

x≤15.9708738

Then you have to round down because you cant have .9 of a person.

So x≤15

Then, Check your solution

8.75+(25.75 x 15)≤420

8.75+386.25≤420

395≤420

That is true. But to make sure that is the maximum add another 25.75

395+25.75≤420

420.75≤420

This is equation is false so, our answer is correct.

The maximum amount of people that can go to the amusement park is 15.

Nelson decides to invest $1,000,000 in a period annuity that earns 4.8% APR
Lyrx [107]

Answer:

<h2> 21years</h2>

Step-by-step explanation:

Amount invested by Nelson = $1,000,000

Interest rate per month = 4.8%

Simple Interest = Principal * Rate * Time/100

simple Interest = $1,000,000 * 4.8 *(1/12)/100

simple Interest = $1,000,000 * 4.8/1200

simple interest = $4,000/ month

Simple interest for one year = $4,000*12 = $48,000

In order to determine the number of years it will take Nelson to earn back his initial investment, we will divide its initial investment by the interest earned on the investment yearly as shown;

amount of years =  $1,000,000/ $48,000

Amount of years = 20.8years ≈ 21years

The sum of additive inverse and multiplicative inverse of 6 is <br>​
nikklg [1K]

Answer:

- \frac{35}{6}

Step-by-step explanation:

The additive inverse is the opposite of 6, that is - 6 ( 6 - 6 = 0 )

The multiplicative inverse is the reciprocal of 6 , that is \frac{1}{6} ( 6 × \frac{1}{6} = 1 )

Thus their sum is

- 6 + \frac{1}{6} = - \frac{36}{6} + \frac{1}{6} = - \frac{35}{6}
