Question 15684: A long-distance phone call costs $0.70 for the first minute and $0.39 for each additional minute or portion thereof. Write an inequality representing the number of minutes a person could talk without exceeding $4.

Let x = number of minutes talked
Total cost of a phone call of x minutes = .70 + .39(x-1)
If total cost does NOT exceed (meaning less than or equal to!) $4.00, then you have
.70 + .39(x-1) <= 4.00
