Answer 2

there are many missing pieces in the given question. will try according to my understanding

I guess its simple interest

p1=12500

p2=15000-12500=2500

t1=t2=3

r1=15%, r2=18%

si1=p1r1t1=12500×3×0.15=5625

si2=p2r2t2=2500×3×0.18=1350

si=si1+si2=6975

she earns 6975 per 3 years

hope this helps
