(a) Complete the ratio table shown. Show your work.

Answer 1

      I = Prnwhere I is the interest, P is the principal, r is the decimal equivalent of the given rate, and n  is the number of years. In this item, we assume that n is equal to 1. Solving for the interests,                $200:     I = ($200)(0.03)(1) = $6                $150:     I = ($150)(0.03)(1) = $4.5The difference between the two calculated interests is $1.5. 
Therefore, you could have earned $1.5 more if you invested $200 rather than $150. 
hope this helps (^>^)
