a. $W(h)=77.6$ b.$h(W)=\frac{W+88}{2.3},$ c. $h(W(h))=h,$ and $W(h(W))=W,$ d.$h(80)=73.04$

$W(h)=50+2.3(h-60),$ a. $W(h)=50+2.3(72-60),$ $=50+2.3(12),$ $=77.6$ b.$h(W)=\frac{W+88}{2.3},$ c. $h(W(h))=\frac{2.3h-88+88}{2.3}=h,$ and $W(h(W))=2.3(\frac{W+88}{2.3})-88=W,$ d.$h(80)=\frac{80+88}{2.3}=73.04$
