An employee at a garden center fills a water tank once a day around noon to a height of 20 inches. The function M models the height of the water in the tank, M(), in inches, z seconds after 12:00 p.m. on Monday as it fills. The function T gives the height of the water in the tank, 7(), in inches, a seconds after 12:00 p.m. on Tuesday as it fills. Here are the equations and graphs of M and T. On Wednesday, the employee gets a second hose and is able to fill the tank twice as fast as Monday. They start filling the tank at exactly 12:00 p.m. The function W models the height of the water in the tank, W (2), in inches, z seconds after 12:00 p.m as it fills. Write an algebraic equation for W. M(z) = 5V

Question
An employee at a garden center fills a water tank once a day around noon to a height of 20 inches. The
function M models the height of the water in the tank, M (), in inches, z seconds after 12:00 p.m. on Monday as it fills.
The function T gives the height of the water in the tank, T (), in inches, z seconds after 12:00 p.m. on Tuesday as it
fills. Here are the equations and graphs of M and T.
On Wednesday, the employee gets a second hose and is able to fill the tank twice as fast as Monday. They start
filling the tank at exactly 12:00 p.m. The function W models the height of the water in the tank, W(), in
inches, a seconds after 12:000 p.m as it fills. Write an algebraic equation for W.
