Consider the problem: Malik makes an investment at 7% simple interest. At the end of 1 year, the total value of the investment is $4280. How much was originally invested?
A. State and explain the formula for simple interest.
B. Practice using the formula. For example, if Malik invested $100 at 7%, it would earn how much in one year and what is the total value of the investment at the end of one year?
C. Relate the given problem to the formula and explain. What are our knowns and what is our unknown? Assign the variable for the unknown. Write a "Let" statement.
D. State the equation that would solve the given problem.
Consider the problem: The perimeter of a rectangular community garden is 144 feet. The length of the garden is 3 feet less than twice the width. Find the dimensions of the garden.
A. What are "dimensions"? State and explain the formula relating the dimensions to the perimeter of a rectangle. Draw a picture to illustrate the problem.
B. Practice using the formula.
C. Relate the given problem to the formula and explain. What is our known and what are our unknowns? Assign variables for the unknown. Write a "Let" statement.
D. State the equation that would solve the given problem in one variable and explain how you would find the other.
l. Consider the problem: Malik makes an investment at 7% simple interest. At the end of l year, the total value of the investment is $4280. How much was originally invested? A.
