The interest is $20 and the amount is $220.
STEP 1: Find an interest by using the formula I=P⋅i⋅t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.In this examplee P = $200, i = 5% and t = 2 years, soIII=P⋅i⋅t=200⋅0.05⋅2=20STEP 2: Find an amount by using the formula A=P+I.Since P = $200 and I = $20 we haveAAA=P+I=200+20=220
Hope this helped have a wonderful day!
