First, let's calculate the average salary by adding them all together, and then dividing the sum by 5:
[tex]\frac{92000+92800+99000+100500+105000}{5}=\frac{489300}{5}=97860[/tex]We have that the average salary is $97,680.
Next, the annual pension is calculated by multiplying the average salary by 1.35% in decimal form:
[tex](97680)(1.35\%)=(97680)(0.0135)=1318.68[/tex]finally, we have that Michael's annual pension is $1318.68
