Math 1 tiny question
posted by Rihanna on .
I posted this question a couple days ago and I also got help but I have one more question , so is the final answer to the question below: 30 downloads would make site A a better deal. No more than 30 and no less or is it equal to 30 and more or equal to 30 and less?
What music plan is a better deal?
site A: $29 per month plus .80 cents per download
site B: $17 per month plus $1.19 per download
write an equation and show how many downloads make site A a better deal.
My answer::
.80x + 29 < 1.19x + 17
after all my other work i got x<30.7
30 downloads would make site A a better deal

any number less than 30.7 will make A a better deal. Try out a few values (like 5 or 10) and check it out.
Check 31 to make sure that at that point B becomes a better deal.
