Answer :
so h(x) is total she has
the other function is interest
if she uses her money to gain interest then she puts in 200 for x in second equation
so subsitute 200 for x
the combined function would be
s(h(x))=(1.05)^(200-1)
basically she put in her savings/gifts and got interst
s(200)=(1.05)^(200-1)
s(200)=(1.05)^(199)
s(200)=16469.1
