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.
.80x + 29 > 1.19x + 17
after all my other work i got x>30.7
30 or more downloads would make site A a better deal
is my answer correct and did i put this sign: > correctly in my equation, please check, thanks
Since we are talking about costs, a better deal is a lower cost, so the inequality should read:
.80x + 29 < 1.19x + 17
The answer is almost perfect...
30.769 rounds to 30.8, although in this case, it does not count because we are talking about integers.
