Malik starts a job at which his starting salary is $25,500 per year. He expects that his salary will
increase by a constant dollar amount annually. In

9514 1404 393

  7 years

Step-by-step explanation:

Malik's salary grows 25,500 in 12 years, so at the rate of ...

  $25,500/(12 yr) = $2125/yr

To get his salary up to 40,000, it must grow by ...

  40,000 -25,500 = 14,500

To grow that much will take ...

  $14,500/($2125/yr) ≈ 6.82 yr

Malik must wait 7 years until his salary is at least $40,000.

At the end of the 7th year, Malik's salary will be raised to ...

  $25,500 + 7·2,125 = $40,375

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
