Work Step by Step

(a) Function of a linear graph is given by \[f\left( x \right)=47x+22\] The function \[f\left( x \right)\] is in the form of \[y=mx+c.\] Slope of the function is 47. On an average, amount spent is increased by 47 per hour spent in the mall. This means that for each additional hour spent at a shopping mall, the average amount spent increases by \[\$47\] per hour. Slope of the function is \[47\]. This means that for each additional hour spent at a shopping mall, the average amount spent increases by \[\$47\] per hour.
