Devorah is filling a pool with a hose. The volume, H, in liters, of water coming out of the hose in m minutes is given by the function H(m)=17.4m. However, it is a sunny day, and water is also evaporating from the pool. Therefore, the volume, V, in liters, of water in the pool mmm minutes after Devorah started filling it is given by V(m)=17m. Let E be the volume of water, in liters, that has evaporated from the pool mmm minutes after Devorah started filling it. Write a formula for E(m) in terms of H(m) and V(m). Write a formula for E(m) in terms of m.
