Answer: 50 mph

Practice Problem 3: Percentage

A soldier receives a 12% pay increase on a monthly salary of $2,500. What is the new salary?

Solution:

• Calculate the increase:
  12% of $2,500 = 0.12 × 2,500 = $300
  
  
• Add the increase to the original salary:
  $2,500 + $300 = $2,800

Answer: $2,800

Practice Problem 4: Ratio and Proportion

In a platoon, the ratio of sergeants to privates is 1:7. If there are 56 privates, how many sergeants are there?

Solution:

• Set up the proportion:
  1 sergeant / 7 privates = x sergeants / 56 privates
  
  
• Solve for x:
  x = (1/7) × 56 = 8

Answer: 8 sergeants

Practice Problem 5: Simple Algebra

A number minus 9 equals 16. What is the number?

Solution:

• Translate to equation: x – 9 = 16
  
  
• Add 9 to both sides: x = 16 + 9 = 25

Answer: 25
