If five notebooks cost $7.25, how much would three notebooks cost?

3 notebooks = $4.35

Step-by-step explanation:

5 notebooks cost $7.25.

We first find out how much 1 notebook costs by dividing 5 by 7.25

7.25/5 = 1.45

Hence, one notebook costs $1.45

To find out how many three notebooks cost, you multiply 1.45 by 3.

1.45 *3 = $4.35  

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.
