You have $100 to spend on downloading podcasts for your Walkman. iTunes charges $2 per podcast, and Spotify charges $5 per podcast. Write an equation that models this situation. If you already downloaded 15 podcasts from Spotify, how many podcasts can you download from iTunes?

The budget is $100, and you have already bought 15 podcasts from spotify, $5 each. I came up with this equation:

You have already spent $75 from the budget so you have to subtract them:

You can only spend $25 from the budget, and since each Itunes cost $2, i came up with this equation:

You can buy 12 podcasts from Itunes, and be left with .50 cents

Thank you! btw can you give me :3

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
