Jacob wants to use an elevator to carry identical packages having the same weight. Each package weighs 3 pounds and Jacob weighs
zzz [600]

Answer:

The required inequality that shows the maximum number of packages is n\leq 67.

Step-by-step explanation:

Consider the provided information.

Each package weighs 3 pounds and Jacob weighs 99 pounds.

let <em>n</em> is the maximum number of package that Jacob can carry with himself in the elevator.

Thus, the total weight of Jacob while having <em>n</em> packages on the elevator is:

3n+99

The elevator can carry a maximum of 300 pounds at a time, therefore.

3n+99\leq 300

Now, subtract 99 from both sides and divide the obtained inequality with 3.

3n+99-99\leq 300-99

3n\leq 201

\frac{3n}{3}\leq \frac{201}{3}

n\leq 67

Thus, the Jacob can carry maximum 67 packages.

Hence, the required inequality that shows the maximum number of packages is n\leq 67.

The salaries of three employees are listed below. Each employee was recently given a raise.
Katena32 [7]
Firstly we need to count how much did the employees earn after the raises:

4% from $41,000 =
= 4/100 * 41,000 =
= 4 * 410 =
= 1644

4,5% from 43,700 =
= 45/1000 * 43,700 =
= 45 * 43,7 =
= 1966,5

3% from 39,700 =
= 3/100 * 39,700 =
= 3 * 397 =
= 1191

Now we need to sum up all the raises:

1644 + 1966,5 + 1191 = 4801,5

So now we can clearly see that answer A ($4,802) is the closest one to the total of all three raises.

You have money in your wallet, but you don't know the exact amount. When a friend asks you, you say that you have 100 dollars gi
Flauer [41]

Answer: 75 < x < 125.

Step-by-step explanation:

Let x be the amount of money in your wallet.  

The phrase "100 dollars give or take 25" means wallet can have money between (100-25) dollars and (100+25) dollars.

i.e. 100-25 < x < 100+25

⇒ 75 < x < 125.

That means the amount of money in your wallet lies between 75 dollars and 125 dollars.

Hence, the inequality to describe the amount of money in your wallet is 75 < x < 125.
