(a) complete the ratio table shown. show your work. (b) how many interest would you have if you deposited $200 than if you if you deposited $150? show your work,

      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 (^>^)

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
