Aphone company charges a flat rate of $15 to make phone calls for a month. they charge $0.10 per minute for each call made. if the want to make at least $60 from one customer, how many minutes do they have to talk

450 minutes

Step-by-step explanation:

15 + 0.1x = 60

15 - 15 + 0.1x = 60 - 15

0.1x = 45

x = 450

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
