A mom is buying her two twin sons new sweaters for the start of the school year. The store is having a sale where if you buy one sweater you get a second identical sweater for 25% off. She can spend a maximum of $30 to buy both sweaters. What is the highest price she can pay for the first sweater?

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

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.
