Suppose that the monthly cost of a long-distance phone plan (in dollars) is a linear function of the total calling time in minutes)
When graphed, the function gives a line with a slope of 0.09. See the figure below.
The monthly cost for 39 minutes of calls is $12.34. What is the monthly cost for 30 minutes of calls?
1234
Monthly cost
(in dollars)
Calling time

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
