15 per minute Here are some hypothetical examples of how much a Lime will cost you: 5 Minutes: 0.75 + 1.00 start fee 1. The 30 cents means that for the minutes it will cost 49.5 or 4950 on and when we add 15, that's going to give us our total bill through october and that total bill comes out to 64.5 or 64 dollars and 50 cents. 39 per minute, though there are some areas where it’s. So at this point we can figure out how much it's going to be in october by plugging in 165 times 30 cents and then adding what we know to be the monthly fee now of 15 point so 165 minutes times. In September, Maggie used 120 minutes and her bill was 51. That means that that monthly fee we've now figured out as 15 dollars. ChitChat Wireless charges 0.30 per minute plus a monthly base fee. Point & Slope Applications ChitChat Wireless charges 0.30 per minute plus a monthly base fee. So when we subtract 36 from both sides, that gives us our x value and our x value is 15 point. If you’re making calls internationally, you will save money with the Stateside add-on. So we'll just call that x because that's what increases whatever 120 times 30 cents to get up to 51, so 30 cents times 120 gives us 36 plus x, equals 51 point. You chat for 30 minutes and when your wireless bill comes around, you’ll find you spent a whopping 90 on that call to Australia On the other hand, if you have the T-Mobile Stateside add-on, that 30-minute call will only cost you 2.10. So that would be 120 times our 30 cents on what we don't know is the monthly fee. Is that we're not told so we're goin to focus on september to start because we know that our bill total was 51 dollars and then we know we're going to charge or get charged 30 cents per minute, and we know that we talked 120 minutes. So what we need to do to be able to figure out the total cost in october is to actually know what that monthly fee. This problem says: chet chet, wireless charges, 30 cents per minute, plus a monthly base fee in september, maggie used 120 minutes and her bill was 51 dollars right and solving an equation to find the total cost of maggie's use of 165 minutes in october.
