Question

Tim uses the equation below to show the number of tickets,the sold after h hours

Answer 1

We know Tim sold tickets with the equation:

`\begin{gathered} t=14h \\ \text{Where t is the number of tickets, h the time in hours and 14 is the rate in tickets/hour} \end{gathered}`

We need to calculate the rate of sold of Sheri to compare with Tim:

`\begin{gathered} \text{Rate betw}een10AMand12PM\text{=}(28-14)/(2)=(14)/(2)=7\frac{tickets}{\text{hour}} \\ \text{Rate betw}een12PMand2PM\text{=}(42-28)/(2)=(14)/(2)=7\frac{tickets}{\text{hour}} \end{gathered}`

Tim sells tickets at 14 tickets/hour and Sheri at 7 tickets/hour, so answer D is correct.
