Answer
Explanation:
Step1: Calculate the raise amount
The raise is 25% of 865. 25% = 0.25 in decimal - form. The raise amount is $0.25\times865$.
Step2: Calculate the new - salary
The new salary is the original salary plus the raise amount. The original salary is 865. The raise amount is $0.25\times865$. So the new salary is $865 + 0.25\times865=(1 + 0.25)\times865 = 1.25\times865$. Also, $0.25=\frac{1}{4}$, so the new salary is $865+\frac{1}{4}\times865$.
Answer:
D. multiply 865 by 1.25, E. add 865 and $\frac{1}{4}$ of 865
