They can be used to estimate the average number of hours \(h\) per week that a household in the United States watches television programs. In all three models, \(t\) is the number of years since \(1985 .\) Hours spent watching television: \(h=0.57 t+54.85\) Hours spent watching talk shows: \(\quad h=0.35 t+4.06\) Hours spent watching game shows: \(h=-0.2 t+3.4\) According to the model, in what year will a household watch television an average of 70 hours per week?
