Avery predicts that the number of horses, $H$, on her farm $t$ years from now will be modeled by the function $H(t)=25(2)^t$, and that the amount of hay, $A$, in tons, that she produces on her farm $t$ years from now will be modeled by the function $A(t)=150(1.5)^t$. Let $F$ be the predicted yearly supply of hay, in tons, available to each horse in Avery's farm $t$ years from now. Note that the hay produced on Avery's farm is used exclusively to feed her horses. **Write a formula for $F(t)$ in terms of $H(t)$ and $A(t)$.** $\qquad F(t)=$ [[☃ expression 3]] **Write a formula for $F(t)$ in terms of $t$.** $\qquad F(t)= $ [[☃ expression 4]]
