Brady is buying two dvds online. one site sells the dvds for $12.75 each and if the total purchase price is more than $25, shipping is free; otherwise, shipping is $3.75. a second site sells the dvds for $11.95 each, plus $2.75 shipping.
if brady chooses the best deal, how much will he pay? (remember to factor in shipping costs.)

He will pay $25.5

Step-by-step explanation:

Hello, I can help you with this

you can solve this finding the total price of each option

Step 1

option 1

the DVDs for $12.75 each and if the total purchase price is more than $25, shipping is free; otherwise, shipping is $3.75.

Brady needs 2 DVDs so

2*$12.75=$25.5

and

$25.5 is more than $25, so the total price is

$25.5

Step 2

option 2

the DVDs for $11.95 each, plus $2.75 shipping.

Brady needs 2 DVDs so

(2*$11.95)+$2.75=$26.65

and

$26.65 is more than $25.5, so Bradly chooses the option 1 ($25.5), He will pay $25.5

I hope it helps, Have a great day.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
