Help Me Solve This you have at most $15.00 to spend. you want to buy a used cd that costs $4.25. write and solve an inequality to find the possible additional amounts you can spend. @Mathematics

hero (hero):

The amount that you spend cannot be greater than 15.00

hero (hero):

you spent 4.25 so x < 15.00 - 4.25

OpenStudy (anonymous):

4.25 X should be less than equal to $ 15

OpenStudy (anonymous):

so would the inequality be 4.25x less than or eqaual to 15.00 ?

hero (hero):

4.25x ? What does that mean? She's going to buy x amount of cds? That's not right

OpenStudy (anonymous):

im going with what sheg said above im a little confused now

hero (hero):

Okay, let me break it down for you a little more. You had 15.00. You spent 4.25 of it. What you have remaining is 10.75. So now, the amount you spend cannot be greater than that, so how do we represent that? We let x = the amount you have and write this: x < = 10.75 Which means that x must be less than or equal to 10.75 that's the only thing you can do.

OpenStudy (anonymous):

then it sud not be less than it will be equal to additional amount, X = $ 10.75

OpenStudy (anonymous):

\[x \le 15 - 4.25\]

hero (hero):

Yeah, I wrote that above already

OpenStudy (anonymous):

oh okay i didnt understand sorry and thankss

OpenStudy (anonymous):

as u know the actual value of cd so we are having exactly $ 10.75 as additional amount to spend.

hero (hero):

x = the amount she spends

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

can you help me graph the solution now ?
