Answer

a.) H(70)=19, therefore it takes 19 hours of study to get a score of 70%. b.) 25 hours of study to get a score of 100%.

Work Step by Step

a.) H(p)=0.20p+5 H(70)=0.20(70)+5 H(70)=14+5 H(70)=19 This means that it takes 19 hours of study to get a score of 70%. b.) H(p)=0.20p+5 H(100)=0.20p+5 H(100)=0.20(100)+5 H(100)=20+5 H(100)=25 hours
