Question 421014: Quick Call charges 18cents per minute for long-distance calls. Econo Phone totals your phone usage each month and rounds the number of minutes up to the nearest 15 minutes. It then charges $7.90 per hour of phone usage, dividing this charge into 15 minute segments if you used less than a full hour. If your office makes 5 hours 3 minutes worth of calls this month using the company with lower price, how much will these call cost?
