$\bf \stackrel{\textit{granny's}}{\cfrac{1}{3}}+\stackrel{\textit{friend's}}{\cfrac{2}{5}}-\stackrel{\textit{sister}}{\cfrac{1}{2}}\implies \stackrel{\textit{using an LCD of 30}}{\cfrac{(10)3+(6)2-(15)1}{30}}\implies \cfrac{30+12-15}{30} \\\\\\ \cfrac{27}{30}\implies \cfrac{9}{10}$

A: For the Dentist, their average income in 30 years is $4,282,200

B: For the Manager, their average income in 30 years is $2,592,000

C: The difference in both their earnings is $1,690,200

Work: So, I just multiplied their average earnings by 30, and that's what their average income will be in 30 years. For the difference, I subtracted the higher earning by the lower earning, and that's the difference.

I hope this helps you. :)
