Mrs. chesney bought 3 games at a cost of $14.99 each. what will she pay including 7% sales tax

Hey there!

The 3 games cost $14.99 each, so multiply to find the cost of the three combined without the tax (the subtotal).

14.99 × 3 = 44.97

To find the amount of tax she will have to pay, we must find 7% of 44.97, the price without the tax added to it (the subtotal).

100% = 1.0

7% = 0.07

Multiply 44.97 by 0.07 for the amount of tax.

44.97 × 0.07 = 3.1479

Add the tax to the cost of the games without tax (subtotal).

44.97 + 3.1479 = 48.1179

Round the amount to the nearest cent. The thousandths place is 7, so it gets rounded up.

The total she has to pay for the games is $48.12.

Hope this helps!

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.
