Juanita borrowed $600 to purchase a new computer. She
was charged 7% interest for two years. She used the
simple interest formula to find the interest.
1 = 600(7)(2)
What error did Juanita make and how will her error affect
the interest she calculates? Explain.
Sample response:Juanita did not change the 7% to the decimal 0.07. When she completes the problem as written, the interest will be greater than the money she borrowed.
