Answer

question continued: what was the total amount the group paid, including tax and tip?

Sales tax=3.00, total paid=47.79

Step-by-step explanation:

37.50 x .08=3.00 sales tax

37.50+3.00=40.50 amount with sales tax added

40.50 x .18=7.29 amount of tip

40.50 + 7.29=47.79 total with tip and sales tax

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
