The overall score will be 25.5. First, you have to turn all of the percentages into decimals: 60% is the same as 3/5 or 0.60 15% is the same as 3/20 or 0.15 25% is the same as 1/4 or 0.25Then you have to multiply the decimal by the score obtained(0.60)*(25)=15(0.15)*(20)=3(0.25)*(30)=7.5After you have all of the final numbers you proceed to add them together and you get 25.5
